-
-
- 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.
