What was this AJ hooked to when you had the demo? A micro, mini, or what? We
have everything from Gavilans to Zilog Z8000's, and 2400 sure would be nice to
get going. I saw an ad in BYTE (when and what brand I don't now remember) for
a 300/1200-212A/2400 Hayes command compatable for around 1K. Is this possible?
I have also heard that there are several different 2400 baud protocols. How
does one distinguish them? Is this another case of whose-got-the-real-protocol
-if-anyone-does?

Preliminary testing of the Fastlink (9600+ baud) dialup modems indicates that they do in fact transfer data at about 9600 baud. Because they are half duplex they are no joy at all to use interactively, but a sustained transfer test shows a speed of 925+ cps (10 bit async). The original test was done using two lines on a common PBX. Having done this we switched to a dialout to AT&T and back in. This went from the local PBX to another PBX, to the local Centrex exchange, back to the remote PBX, back to the local PBX. Same result. We then forced a loop out onto out leased (barely) voice grade lines and back. Still okay. The next test will be uucp with the path: local exchange -> longline -> local exchange -> PBX -> PBX. I will report the results of this test in terms of transfer speed as soon as I return (next year). -- billD (..seismo!rochester!steinmetz!crdos1!davidsen) (davidsen@GE-CRD.ARPA) "It seemed like a good idea at the time..."
