///1ASSIGN
Syntax:
ASSIGN D:[=[{D:|<device>[<unitnum>]:[<slicenum>]}]][,...]
Explanation:
Using the ASSIGN command, on a RomWBW system the drive
letter assignments can be listed or changed.
Drive letters can be swapped, assigned to devices or slices
or unassigned.
Multiple (un)assignments can be concatenated using commas.
A device or slice can only be assigned to a single drive
letter.

///1MODE
Syntax:
MODE /?
MODE COM<n>:
[<baud>[,<parity>[,<databits>[,<stopbits>]]]] [/P]
Explanation:
MODE is used to display and/or modify the configuration
of a serial device of a RomWBW system.
<baud> is numerical baudrate
<parity> is (N)one, (O)dd, (E)ven, (M)ark, or (S)pace
<databits> is number of data bits, typically 7 or 8
<stopbits> is number of stop bits, typically 1 or 2
/P prompts the user prior to setting new configuration
Notes:
Parameters not provided will remain unchanged.
The device must support the specified configuration.

///2Examples
A>MODE /?
Display command usage
A>MODE
Display configuration of all serial ports
A>MODE COM0:
Display configuration of serial unit 0
A>MODE COM1: 9600,N,8,1

///1SYSCOPY
Syntax:
SYSCOPY <dest>[=<src>]
Explanation:
SYSCOPY is used to copy a system image to or from the re-
served tracks of a disk on a RomWBW system.
This is used for RomWBW adaptions of CP/M 2.2 and CP/M 3.
<dest> and <src> may be a drive or a file reference
If <src> is not specified, the system image will be read
from the current drive

///1FAT
Syntax:
FAT DIR <path>
FAT COPY <src> <dst>
FAT REN <from> <to>
FAT DEL <path>[<file>|<dir>]
FAT MD <path>
FAT FORMAT <drv>
CP/M filespec: <d>:FILENAME.EXT (<d> is CP/M drive letter)
FAT filespec: <u>:/DIR/FILENAME.EXT (<u> is device #)
Explanation:
FAT is used to manipulate and exchange files with a FAT
(DOS) filesystem. It runs on any HBIOS hosted CP/M implemen-
tation.
The first parameter defines the action to perform on the FAT
filesystem.

///2Examples
A>FAT DIR 2:/
Shows the root directory of device 2
A>FAT COPY C:TEXT.TXT 2:/BOOK/
Copy the file TEXT.TXT from CP/M drive C: to the directory
/BOOK on device 2.
A>FAT COPY 2:/BOOK/TEXT.TXT C:
Vice versa

///3Notes
Partitioned or non-partitioned media is handled automatical-
ly. A floppy drive is a good example of a non-partitioned
FAT filesystem and will be recognized. Larger media will
typically have a partition table which will be recognized by
the application to find the FAT filesystem.
Although RomWBW-style CP/M media does not know anything
about partition tables, it is entirely possible to have
media that has both CP/M and FAT file systems on it. This
is accomplished by creating a FAT filesystem on the media
that starts on a track beyond the last track used by CP/M.
Each CP/M slice on a media will occupy a little over 8MB.
So, make sure to start your FAT partition beyond
(slice count) * 8MB.
The application infers whether you are attempting to refer-
ence a FAT or CP/M filesystem via the drive specifier (char
before ':').
A numeric drive character specifies the HBIOS disk unit num-
ber for FAT access. An alpha (A-P) character indicates a
CP/M file system access targeting the specified drive let-
ter. If there is no drive character specified, the current
CP/M filesystem and current CP/M drive is assumed.
For example:
2:README.TXT refers to FAT file README.TXT on disk unit #2
C:README.TXT refers to CP/M file README.TXT on CP/M drive C
README.TXT refers to README.TXT on current CP/M drive
Files with SYS, HIDDEN, or R/O only attributes are not given
any special treatment. Such files are found and processed
like any other file. However, any attempt to write to a
read-only file will fail and the application will abort.
It is not currently possible to reference CP/M user areas
other than the current user. To copy files to alternate user
areas, you must switch to the desired user number first or
use an additional step to copy the file to the desired user
area.
Accessing FAT filesystems on a floppy requires the use of
RomWBW HBIOS v2.9.1-pre.13 or greater.
Files written are not verified.
Wildcard matching in FAT filesystems is a bit unusual as im-
plemented by FatFs. See FatFs documentation.

///1TUNE
Syntax:
TUNE <filename>
Explanation:
TUNE plays PT2/PT3/MYM sound files.
<filename> of sound file to load and play
Filename extension determines file type
(.PT2, .PT3, or .MYM)
Notes:
- Supports AY-3-8910, YM2149, etc.
- Max Z80 CPU clock is about 8 MHz or sound chip will not
handle speed.
- Higher CPU clock speeds are possible on Z180 because extra
I/O wait states are added during I/O to sound chip.
- Uses hardware timer support on systems that support a timer.
Otherwise, a delay loop calibrated to CPU speed is used.
- Delay loop is calibrated to CPU speed, but it does not com-
pensate for time variations in each quark loop resulting
from data decompression.
An average quark processing time is assumed in each loop.
- Most sound files originally targeted MSX or ZX Spectrum
which used 1.7897725 MHz and 1.773400 MHz respectively for
the PSG clock. For best sound playback, PSG should be run at
approx. this clock rate.
