Thanks for the info on the 4-Port LAN adapter.? I've sent Terry an email asking about it. David

Good point as always. Need to dig out my break-out box for that. Get Outlook for iOS<https://aka.ms/o0ukef> ________________________________ Sent: Tuesday, August 25, 2020 9:42:21 PM To:

Might want to try looping back the RTS/CTS and the DTR/DSR pairs on the modem.? That might fool it to work with 3-wire RX/TX/Gnd RS-232

Thanks Mark. I never inspected the modems I have, but it’s worth a look based on your experiences. Get Outlook for iOS<https://aka.ms/o0ukef> ________________________________ Sent: Tuesday, August

Rich, I had a number of Optima 144 modems, and they all had severe PCB damage from leaked surface mount caps--more damage than I had the patience to try to fix. I was able to rescue/preserve a

Yes. Synchronet 3.17 running on XP, which is Telnet only. It uses “COM-to-telnet” bridge software to support POTS. I had a spare PC handy so I set it up as a quick test to give the Z80MC something

Just a quick update on this. I have a BBS (Synchronet) running enough that I can dial-in from another PC and connect properly. I started with the Hayesmodem 300, which was painful, and then changed to

I have p112 and a question about "Terry’s Ethernet p112 serial adapter board".? What did you get from Terry's site to connect the p112 serial to the Ethernet?? Just the "LAN Terminal

The last several are good examples of how you can get from the 'net to a old school system being CP/M based on a PDP-11 that is sans native networking.? The interface between the network and the 80

Hi, I telnet to my p112 cp/m system console, via Terry’s Ethernet p112 serial adapter board. It even automatically powers & boots upon establishment of the telnet

Chiming in here: I still use LINKSYS WRT-54G wireless routers running DD-WRT. They all support TELNET logins (port 23), which is the insecure predecessor to SSH (port 22). I use TELNET to log into

Bill, There is no known to me TELNET for Z80, those BBS ran either DOS or a flavor of unix like software [Netware, Venix, Minix] on 8088 or later than 1986ish maybe 286 or 386 hardware. Telnet to a

A direct solution is instead of POTS (old skool term for the basic phone service) compatible modem at the end of a serial line use one of the serial connected Ethernet or Wifi modems. Or use a

The “modem emulator” programs, like the link I sent the other day, will basically traffic serial over Ethernet using a PC, sort of like the all-in-one solutions from Olimex and Wiznet (??) which

I can't help thinking telnet is a good answer to this. it gives you a tty interface over the internet with simple hardware and can be run on small systems. I know there are telnet bbs's - i just
