EXMODE
Examine or Change Device Initialization Mode

arglist
Description
exmode is an enhanced verison of the xmode utility, and is useful for
changing initialization parameters specific to CoCo 3 window descriptors
and enhanced ACIA device descriptors.
Exmode is very similar to the tmode command.
Tmode only operates on
open paths so its effect is temporary. Exmode actually updates the
device descriptor so the change persists as long as the computer is
running, even if paths to the device are repetitively opened and
closed. If exmode is used to change parameter(s) and the COBBLER
program is used to make a new system disk, the changed parameter
will be permanently reflected on the new system disk.
Exmode requires a device name to be given. If no arguments are
given, the present values for each parameter are displayed,
otherwise, the parameter(s) given in the argument list are
processed. Any number of parameters can be given, and are separated
by spaces or commas.

backspace-space-backspace sequence (default).
-bsb
no erase on backspace: echoes single backspace only
bsl
Backspace over line: lines are "deleted" by sending
backspace-space-backspace sequences to erase the same

"pag" parameter for definition of screen size. Output
can be resumed by typing any key.
-pause

null=n
Set null count: number of null ($00) characters
transmitted after carriage returns for return delay.
The number is decimal, default = 0.
pag=n
Set video display page length to n (decimal) lines.
Used for "pause" mode, see above.

Numeric value of character in hexadecimal. Default = 0D
eof=h
Set end-of-file input character. Numeric value of
character in hexadecimal. Default 1B.
type=h
ACIA initialization value: sets parity, word size, etc.
Value in hexadecimal. Default 15
reprint=h
Reprint line character. Numeric value of character
in hexadecimal.
dup=h
Duplicate last input line character. Numeric value of
character in hexadecimal.
psc=h

code for baud rate: 0=110 1=300 2=600 3=1200 4=2400 5=4800
6=9600 7=19200
