It does have Telebit's proprietary PEP protocol, a level of MNP (I think level 3), and another one. However, the Telebit queries the CALLING modem to see if it's capable of any of the compression schemes it has. If the CALLING modem can't do any of the special goodies, the Telebit just pumps stuff out at the CALLING modem's baud rate. The interface speed betwixt the Telebit and its host computer stays locked at whatever you set (sure makes writing software easier). The T1000 is a subset of the T2000, T2500, and TrailBlazer/TrailBlazer+ families. It has a maximum baud rate of 9600 (althought PEP protocol does give a throughput of 19,200). The TrailBlazer Plus has just about every protocol around, and can be upgraded via a ROM change. I'm sorry I don't have all the T1000 data handy (my office looks like a tornedo went through here) and the manual's buried somewhere. Now if the Hayes modem, when set to V.32 mode, will ONLY deal with V.32 modems, you've got a problem. I can't really believe that it would do such a thing, since Hayes usually has their heads on straight. But I _have_ seen modems such as that (if you set a protocol in the modem, that's all it can talk). I know that the Telebits are smart enough to adapt to whatever the calling modem is capable of, and that's why I use a Telebit. That's why lots of Usenet sites use Telebits -- they're flexible. They also have UUCP "g" protocol and Kermit spoofing internally, so your processor doesn't have to deal with it (speeds things up just a bit more). On the economic side, you can usually get Telebits cheaper than Hayes modems. ---------------------------------------------------------------------------- [- O] Rick Stevens ?
