I have verified the modem and RS telecom cable's connectivity, at least so far as the ability to dial out. I can auto-dial with an entry in ADRS.DO from within TELCOM.
With the help of a M:M gender-changer, ribbon cable from 1982 and Zoom V34X modem I have been able to control the modem within TERM and even successfully connected to a few dial-up BBS, thanks to the listings in the Telnet BBS Guide. https://www.telnetbbsguide.com/ I have tried various STAT settings but noticed that 98N1D (19,200 BPS, 8 bit words, No parity, 1 stop bit, disable XON/OFF) which I would consider default and which works with most BBSs did not have success with the M100. I got a lot of graphics characters, it seemed. With settings of 88O1E I contacted a BBS and made pretty good headway until they asked what terminal I was emulating. My choices were ADM3A or ANSI, neither of which were effective. Does anybody know what this terminal emulates? VT100? Thanks again for your help. -CH-
