Here's where I'm at:
1. Fire up Minicom (19200, 8N1, no flow control)
2. Minicom is Offline
3. Fire up M100
4. CTL-C to enter CP/M
5. Label-F1-Label (Sc to S)
6. Label-F2-Label (Cu to S)
7. Label-F3-Label (selecting RS23) to "initialize RS232"
8. Minicom is Online
9. Label-F3-Label (selecting M100) so you can type on the M100
10. in CP/M, stat con:=uc1:
A>dir
sorta works...

Hmmm... off to trying a lower baud rate via TELCOM

Yes, 19200 (98N1D) as stated in 'Initialising RS-232"

however, maybe one can initialise in TELCOM to a different baud rate...

What is the default baud rate? Are the other settings - 8n1?

Yes, the IO byte is fully implemented in M100 CP/M. Use 'stat
con:=uc1:'for serial port input. Currently no way of altering baud
rate, on the to-do list.

over on Vcf, I asked about whether serial over console was possible
and they said:
CP/M is basically indifferent about the details of the console,
that being contained within the BIOS created by the vendor for
the platform you're running on. I'm not familiar with the M100
platform, but if it has a serial port, *AND* the vendor
implemented CP/M "I/O redirection" in their BIOS, then you can
use STAT to re-assign the console to a serial port. You have to
determine which of the devices is the serial port, but then
you'd issue a command like "STAT CON:=TTY:" after which you
should see the "A>" prompt on the serial port. Note that if you
reassign the console to the wrong device, you won't be able to
issue the command to return to the original console device
(e.g. "STAT CON:=CRT:"), and will probably have to RESET and
reboot. Read up on the STAT command, as it can show you the
available device assignments, current assignments, etc.
Which kinda makes sense, but what is the serial port called? CON is
already TTY, so that's not it. Also, how do I set the baud rate and
suchlike in CP/M... anyway, " it has a serial port, *AND* the
vendor implemented CP/M "I/O redirection" in their BIOS"... does
anyone know if this is the case?
Thanks,
Will
