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.

I am using 'stat con:=uc1:' to do the re-direct. It seems to work for a minute, then stops. I am using minicom in Linux and it works reliably using the REXCPM 'F3 toggle' feature to re-direct only the screen output (19200 8N1). Has anyone else tried doing this successfully?

I?m glad to see this post because I honestly had been thinking a while back that ?I wish there was a way to use a ps/2 keyboard with my MVT100 board as a full-blown terminal? but didn?t try anything because I?m not familiar enough with CP/M to know how to redirect the console like that. What baud rate does it end up using when you do this? jim From: M100 <[email protected]> On Behalf Of Tom Hoppe Sent: Tuesday, November 16, 2021 10:50 To: [email protected] Subject: [M100] Re-directing CP/M console to serial port in REXCPM CAUTION External Sender: Do not click links or open attachments unless you recognize the sender and know the content is safe.

I am hoping to get rolling and finish off the font redesign for the MVT100 board I was working on last winter. I think Stephen had started sharing the interim firmware I made which had initial M100 graphic characters added and some minor readability improvements to some of the characters (particularly the numbers 6 and 9). I haven't been keeping up with this list, just filing the messages in the hope I'd pull myself up and start reading them - it's quite the backlog so I don't know if I will get there or not, so I don't know if I've missed any big developments in the REX or REXCPM worlds - I think the big one I was hoping for was a new 4mb CP/M image with more file handles/descriptors... and of course, the first message I read in a long time this morning stirred some hope of using the M100 CP/M with an external keyboard when stationary! Glad to see you all again, and hope I can stay on top of things for a while. jim ------------------------------ Message: 4 Date: Tue, 16 Nov 2021 14:34:02 -0500 From: Stephen Adolph <[email protected]> To: [email protected] Subject: Re: [M100] Re-directing CP/M console to serial port in REXCPM Message-ID: <camcmnv6jkspfla9eve8ccwh3u+p_n2fzlxjscmxp7jf7hao...@mail.gmail.com> Content-Type: text/plain; charset="utf-8" I think Philip Avery is probably best to comment on to what degree that is supported. It is a good question.
