[Coco] Internet/BBS connectivity via Coco1

[Chris Osborn]

> I'm fairly sure that my college roommate and I got two 300 baud modems to talk to each other over once over phone cable strung across our dorm room with no dial tone present between a CoCo 3 and an Apple ][, but maybe I'm remembering more success than we actually achieved.  

I've done it too, it's not hard. The only trick is convincing the dialing modem to dial without waiting for the dial tone, then just do ATA on the other modem.
