This document aims to provide a Quick Reference Guide for the VT132 terminal/modem module for RC2014-style
|
||||||
|
computers.
|
||||||
|
|
||||||
|
This is a LaTeX document, so a working LaTeX installation is needed to compile it.
|
||||||
|
|
||||||
|
A compiled version is available as ```vt132.pdf```.
|
||||||
|
|
||||||
|
To edit the document in the LaTeX editor Kile, a kile project file (```vt132.kilepr```) is provided.
|
||||||
|
|
||||||
|
To compile the file, just run ```pdflatex vt132.tex``` (2 times to get the references right) and you get the ```.pdf``` file.
|
||||||
|
|
||||||
|
The script ```clean.sh``` can be used to remove all intermediate files.
|
||||||
|
|
||||||
|
The Debian/Ubuntu package ```texlive-fonts-extra``` (besides ```texlive``` as the base TeXlive package) is needed to provide the font "Linux Libertine".

|
||||||
|
\section{Installation}
|
||||||
|
|
||||||
|
To install the VT132 in a RC2014 or a compatible system, place it in a standard or extended bus socket.
|
||||||
|
|
||||||
|
If your backplane does not offer an extended bus, the modem cannot be used via bus pins, instead the modem FTDI header has to be used.
|
||||||
|
The extended bus pins are not used for other purposes.
|
||||||
|
|
||||||
|
\textbf{On a new VT132, the NVR (Non-volatile RAM) is not initialized.}
|
||||||
|
|
||||||
|
At power-on or reset, following the \textbf{Wait} message, a new VT132 will display \textbf{Error} along with a series of bells.
|
||||||
|
This is expected because the NVR has not been initialized.
|
||||||
|
Once you write settings to the NVR, this error should not persist.
|
||||||
|
|
||||||
|
\section{Jumper settings and headers}
|
||||||
|
|
||||||
|
The board features the following jumpers:
|
||||||
|
|
||||||
|
\begin{tabular}{p{7em} | p{0.71\textwidth}}
|
||||||
|
\hline
|
||||||
|
\textbf{Jumper} & \textbf{Function} \\
|
||||||
|
\hline
|
||||||
|
JP1 RxA & \multirow{2}{*}{Connect terminal to port A on bus pins} \\
|
||||||
|
JP2 TxA \\
|
||||||
|
\hline
|
||||||
|
JP3 RxB & \multirow{2}{*}{Connect modem to port B on ext. bus pins} \\
|
||||||
|
JP4 RxB \\
|
||||||
|
\hline
|
||||||
|
JP5 Pwr FTDI & Connect Power to FTDI +5V pin \\
|
||||||
|
\hline
|
||||||
|
JP6 Pwr Modem & Connect Power to modem FTDI +5V pin \\
|
||||||
|
\hline
|
||||||
|
\end{tabular}
|
||||||
|
|
||||||
|
Enabling JP1 and JP2 is highly advised, as the VT100 terminal serial connection is not available on a FTDI header.
|
||||||
|
|
||||||
|
If you want to provide power to, or take power from either of the 6 pin headers then JP5 and JP6 will provide power
|
||||||
|
or isolate the \texttt{Vcc} pin in the \texttt{FTDI Program} and \texttt{Modem Port B} 6-pin headers respectively.
|
||||||
|
|
||||||
|
\textbf{Warning:} You should normally only connect one power source to the system at a time.
|
||||||
|
|
||||||
|
\begin{tabular}{ c | p{0.38\textwidth} || c | p{0.38\textwidth}}
|

\end{tabular}
|
||||||
|
|
||||||
|
If your RC2014 serial module uses the RTS/CTS pins, you can disable JP3+4 and use jumper wires to connect the \textbf{Modem Port B} of the VT132 to your serial module,
|
||||||
|
as no bus pins are assigned to RTS/CTS.
|
||||||
|
|
||||||
|
The \textbf{FTDI Program} header outputs debug messages from the ESP32 microcontroller. You can connect another terminal (or a PC) to watch the debug output.
|
||||||
|
The output uses 115.200 baud, 8 data bits, no parity, 1 stop bit (8-N-1).
|
||||||
|
|
||||||
|
It is also possible to flash the ESP32 via this header. To enable the \textit{programming mode}, press and hold \textbf{Reset}, press and hold \textbf{Prog}, release \textbf{Reset}
|
||||||
|
and release \textbf{Reset}. Another firmware can now be uploaded, eg. via \texttt{esptool}.
|
||||||
|
|
||||||
|
\newpage
|
||||||
|
\section{Buttons}
|
||||||
|
|
||||||
|
The VT132 module offers two buttons:
|
||||||
|
|
||||||
|
\begin{itemize}
|
||||||
|
\item Reset
|
||||||
|
\item Prog
|
||||||
|
\end{itemize}
|
||||||
|
|
||||||
|
The hardware \textbf{Reset} button on the PCB reboots the ESP32 (EN line reset). This will cause both the VT100 terminal and the modem to reset.
|
||||||
|
Any unsaved settings (terminal and/or modem settings) will be lost.
|
||||||
|
|
||||||
|
\textit{Note:} The computer connected to the VT132 will not be reset, so after the reset, you will be in the same program as before.
|
||||||
|
|
||||||
|
The hardware \textbf{Prog} button is used to switch the baud rate of the modem. After each press of this button, the modem outputs its new
|
||||||
|
baud rate to the serial port - so you can press this button repeatedly until you can read your baud rate.

\chapter{Introduction}
|
||||||
|
|
||||||
|
The VT132 terminal module is a RC2014 compliant module which makes it possible to use a RC2014 as a stand-alone computer
|
||||||
|
as it provides keyboard input and VGA display output.
|
||||||
|
|
||||||
|
It also provides WiFi modem emulation which enables the use of a terminal program (like Kermit or QTerm on CP/M) for
|
||||||
|
transferring data, controlling a remote computer or logging into a BBS.
|
||||||
|
|
||||||
|
This Quick Reference Guide lists the options and commands needed for everyday use of the VT132.
|
||||||
|
|
||||||

\chapter{The Modem}
|
||||||
|
|
||||||
|
\section{Background}
|
||||||
|
|
||||||
|
Unlike the VT100 terminal, the modem does not try to faithfully emulate any particular original device.
|
||||||
|
|
||||||
|
Instead it is designed to provide an MVP (minimum viable product) providing a modified Hayes 'AT' compatible command set for connecting over Wi-Fi via TCP/IP sockets with an optional Telnet protocol layer.
|
||||||
|
|
||||||
|
\begin{itemize}
|
||||||
|
\item The original 'AT' command set was strictly in upper case. This is because the bit sequence of the ASCII values for 'A' and 'T' have a specific property that enables autobaud detection of the connection to the data terminal equipment (DTE).
|
||||||
|
\item \textbf{The modem only responds to 'AT' commands in upper case.}
|
||||||
|
\item Commands are terminated by \texttt{<CR>} (carriage return, \texttt{<ctrl>-m}, \texttt{0x0D}, decimal 13) usually generated by the \texttt{Enter} or \texttt{Return} key on your keyboard.
|
||||||
|
\item Commands can by edited, before pressing \texttt{<CR>}, using \texttt{<BS>} (backspace, \texttt{<ctrl>-H}, \texttt{0x08}, decimal 8) to erase the previous character entered. You may need to configure the terminal to generate \texttt{<BS>} when you press the \texttt{Backspace} or \texttt{<-} key on your keyboard.
|
||||||
|
\item The 'AT' command processor is based on a finite state machine (FSM). If you type anything that is not recognized by the rules of the FSM you will immediately see an \texttt{Error} message.
|
||||||
|
\end{itemize}

The modem has a total of 51 'S' registers, \texttt{S0} to \texttt{S50}.
|
||||||
|
|
||||||
|
Most of them are undefined and unused. The following table lists all defined registers that are used by the VT132 modem part.

\section{Telnet}
|
||||||
|
|
||||||
|
\subsection{Telnet options}
|
||||||
|
|
||||||
|
The VT132 supports the following Telnet options:
|
||||||
|
|
||||||
|
\begin{itemize}
|
||||||
|
\item SGA (Suppress Go Ahead)
|
||||||
|
\item ECHO
|
||||||
|
\item BIN (Binary Transmission)
|
||||||
|
\item NAWS (Negotiate About Window Size)
|
||||||
|
\item TERMINAL-TYPE
|
||||||
|
\end{itemize}
|
||||||
|
|
||||||
|
Each Telnet Option is negotiated in via a request/response exchange described as \textit{Do/Don't} (request) and \textit{Will/Won't} (response). Trying to understand how these work for each Option usually requires reading the RFC and extreme patience and experimentation.
|
||||||
|
|
||||||
|
Usually you either want an Option completely \textbf{On} (Do/Will) or \textbf{Off} (Don't / Won't).
|
||||||
|
|
||||||
|
Setting the supported Options and their default values are defined via specific 'S' Registers \vref{sregister}.
|
||||||
|
|
||||||
|
In summary the defaults are:
|
||||||
|
|

The \texttt{TERMINAL-TYPE} must be known by the remote system to be recognised.
|
||||||
|
|
||||||
|
When connecting to \texttt{telnetd} on MacOS I use \texttt{vt100+} from the \texttt{terminfo} database which provides support for color over and above the standard \texttt{vt100} terminal type, making text applications like \texttt{htop} work as expected and in color.
|
||||||
|

||||||
|
\subsection{Enabling Telnet Protocol}
|
||||||
|
|
||||||
|
Telnet protocol is \textbf{not} enabled by default.
|
||||||
|
|
||||||
|
\begin{itemize}
|
||||||
|
\item To enable the Telnet protocol you must manually set 'S' Register S15 to 1 with \texttt{ATS15=1}
|
||||||
|
\item To disable the Telnet protocol you must manually set 'S' Register S15 to 0 with \texttt{ATS15=0}
|
||||||
|
\end{itemize}
|
||||||
|
|
||||||
|
The Telnet protocol is applied to both \textbf{outgoing} connections 'Dialed' with ATD and \textbf{incoming} connections 'Answered' with \texttt{ATA} or Auto-answer.

||||||

\section{Answer Mode}
|
||||||
|
|
||||||
|
Listening for incoming TCP/IP socket connections is \textbf{not enabled} by default.
|
||||||
|
|
||||||
|
\begin{itemize}
|
||||||
|
\item To \textbf{enable} listening for incoming TCP/IP socket connections you must manually enter \texttt{AT\&A} to \textit{Enable Answer Mode}.
|
||||||
|
\item Answer Mode will remain enabled, and can only disabled by an \texttt{ATZ} (Soft Reset), hardware reset or power-cycle.
|
||||||
|
\item Incoming TCP/IP socket connections will cause the modem to respond with \texttt{RING}, repeated every three (3) seconds.
|
||||||
|
\item As each \texttt{RING} occurs the Ring Counter in \texttt{S1} is incremented by one (1).
|
||||||
|
\item The user can \textit{Answer} the incoming call at any time with \texttt{ATA} and the modem will accept the TCP/IP socket connection and enter \textbf{Data Mode}.
|
||||||
|
\item If the \textbf{Number of rings before Auto-Answer} is set in \texttt{S0} to a number greater than zero (0 = never) and \texttt{S1} is greater-then-or-equal to \texttt{S0} the modem will \textit{Auto-answer}: accept the TCP/IP socket connection and enter \textbf{Data Mode}.
|
||||||
|
\item If Telnet protocol is enabled by \texttt{ATS15=1} then the Telnet Protocol will be negotiated with the remote host after the modem enters \textbf{Data Mode}.
|
||||||
|
\item The user can \textit{Hangup} an incoming call by sending the Escape Sequence \texttt{+++} (with guard times) to return to \textbf{Command Mode} and then sending \texttt{ATH} to \textit{Hangup}.
|
||||||
|
\item A Hangup \texttt{ATH} will reset the Ring Counter in \texttt{S1} to zero (0).

\section{The Set-Up Screens}
|
||||||
|
|
||||||
|
The Set-Up screens imitate the same functions on a real DEC VT100 terminal.
|
||||||
|
|
||||||
|
Use \texttt{F1} to toggle the help display which shows all keys. \\
|
||||||
|
Use \texttt{5} to advance to the next screen.
|
||||||
|
|
||||||
|
\subsection{Set-Up A}
|
||||||
|
|
||||||
|
This page shows the tab stops and offers to toggle \textbf{80/132 columns} text display and also switching between
|
||||||
|
\textbf{online} and \textbf{local mode}.
|
||||||
|
|
||||||
|
In \textbf{online mode}, the terminal is connected to the computer via the serial port.\\
|
||||||
|
In \textbf{local mode}, the terminal can be used to connect directly to the modem using the \textit{Quick Settings menu} (see \vref{quicksettings}).
|
||||||
|
|
||||||
|
Use \texttt{Shift-S} (capital \texttt{S}) to save and \texttt{Shift-R} (capital \texttt{R}) to recall the settings from NVS.
|
||||||
|
|
||||||
|
\subsection{Set-Up B}

The main function of the VT132 is the terminal. It functions as a VT100 terminal but is also capable of
|
||||||
|
ANSI color sequences and can also display DOS \texttt{ANSI.SYS} compatible sequences.\\
|
||||||
|
Alternative personalities like ADM-3A or VT-52 are also available.
