Since my acquisition included a modem cable I have been investigating the modem's capabilities and the TERM program. In the process I noticed that commands are fairly rudimentary and inflexible; there is no Hayes command set, for example.
I looked at the DocGarden documentation including the Covington ROM maps (what a task!) and found reference to routines but not the actual routines themselves. But after looking at the data sheet for the MC14412 chip I conclude that there isn't much "smarts" in the silicon. However, I am famous for being wrong, so if anyone has knowledge on the subject please advise. In the meantime I will investigate communications through the serial port, as I have external modems. I'll need to find a gender-changer somewhere, though. While investigating this topic I came across a related posting, which I pass along in case anyone is interested: https://arstechnica.com/information-technology/2015/08/surfing-the-internet-from-my-trs-80-model-100/ Thank you as always for your help and advice. -CH-
