Thanks Ron for your feedback using M100 CP/M. I'd forgotten about the
'returning to User 0' problem, so that's on my To Fix list.
Also intended for a future release is retaining Function key settings
for subsequent cold boots, so Scroll lock/std, Cursor full time/std,
RS-232 baud rate, etc will be retained.

So last year I played with using a Linux or Windows computer as a
terminal using REXCPM. I found that doing a 'stat con:=uc1:’ does
indeed redirect the CP/M console I/O to the serial port and was
somewhat successful using it that way. Doing 'stat con:=crt:’ sets
only the output to the RS232port. ‘Stat con:=tty:’ sets I/O back to
the M100 keyboard and screen. I did have to configure a terminal type
for some screen oriented software and usually chose VT52 ( H19) or
VT100 if available, then used a terminal program such as minicom
(VT100) or, on a DOS machine I tried Procomm+ which had older
terminal types available like H19, VT52, ADM and Televideo. I used
9600 baud , no parity, no flow control to setup the serial port using
the PC terminal program and the M100 Telcom program (88N1D) . I think
I also tried 19200 baud with no problem.
Only problems I found were:
1. Need to use the F1 to toggle Sc L to Sc S to keep the screen from
halting after every 8 lines. Some programs also work better if F2
is used to changed to Cu S.
2. Needed to re-adjust the CPM software to expect 24 lines/80 col
instead of 8lines/40col ( if your Model 100 CPM SW had been
adjusted to 8 screen lines.
3. Some Software ( Infocom games?) needed to see one <CR> from the
model 100 keyboard before it switched to the full sized keyboard
attached to the PC. Weird.
Also I noticed that whenever a warm boot occurs, via CTRL-C or by a
program, the user number reverts to user 0 regardless of the user you
are logged into. This makes it less convenient to run programs from
any user other than user 0. I don’t “think” a warm-boot I supposed to
change the user number back to 0. I know it doesn’t do that on any
8- bit CP/M machine I own (Kaypro 2/4/10, Osborn I , NEC PC8801A,
Televideo TPC-1). I think this may have been discussed a while back
on this mailing list….
I really enjoyed trying my old CP/M software on the M100. Brings back
my late 70’s early 80’s memories of personal computer development.
We’ve come a long way since then.
Hope you all have a great holiday season.
