Augh. No amount of work will make this thing connect to any of my other computers! I even tried making my own null-modem cable after the RadioShack one didn't work(according to the page at http://www.club100.org/library/doc/cables.html) and nothing has worked! Been trying to use Teeny... I'm going to try to connect with telcom software just to see if the serial port on the M-10 works. I think it might be a ROM difference that's making Teeny not work.
