The Supra 1200at sounds like the same idea that Nite Lite Systems sells as an interface to the Avatex 1200: a re-invention of the R:Verter concept. Maybe if you can find a driver for the R:Verter, it will work with the Supra as well. Certainly an ordinary RS-232 driver won't work. Basically, the R:Verter is a TTL to RS232 level converter. (Cheap, huh!?) It sits on the SIO line, which is basically a TTL serial Async interface without all the usual handshake signals. The R:Verter lets you tie it to a device that expects RS-232 levels. All you need is a piece of software (driver) to patch it in to the normal R: interface that the CIO knows about. (Somebody who really knows what they are talking about might care to comment at this point, or better yet, to supply a copy of the R:Verter driver.) If you are REALLY stuck, you might try to prevail on the good nature of Paul Swanson, owner of Nite Lite Systems, for help. I believe he DOES supply a driver with his modified Avatex. Paul can be reached via BBS at (617) 663-4221. He does have a voice line but doesn't like to be pestered there as he is quite busy trying to make a living as an Atari sales and service dealer and creator of fine hardware/software products for Ataris. (If you have no way of reaching him via the BBS -- e.g. 'cause you can't get your new modem to work -- let me know and I will send you his voice line number.) -John Sangster / jhs@mitre-bedford.arpa
