v1.0 - E.Meyer 1/85
RSXDIR is a simple program that will list the names of all the RSXs
(Resident System Extensions) currently installed in a CP/M Plus (3.0) system.
It takes no arguments; simply type RSXDIR.
Example: on my Osborne Executive, I might find:
A>rsxdir
RSXDIR 1.0 - E.Meyer 1/85
BACKSP10
EXCLOCK
LOADER
This informs me that I have two RSXs installed, my BACKSPAC RSX (which lets my
Okidata printer backspace) and George Peace's EXCLOCK, which displays the
clock on the screen. The LOADER RSX is part of CP/M Plus, and remains present
when other RSXs are.
NOTE: CP/M 2.2 EMULATION
RSXDIR is for CP/M Plus only; if it is run on an earlier version, it will
display the message "Not a CP/M Plus System". (It checks the version number
with BDOS 12.) This can be unfortunate if you have installed one of the RSXs
which "mimics" CP/M 2.2 for compatibility purposes: RSXDIR may not work.
There is a simple patch. Using SID or equivalent, change the byte at
0126h in RSXDIR.COM from 30h to 00h. Then RSXDIR will operate no matter what
the version number appears to be.
