V.42 seems to be the standard error checking now. Not that many vendors have it today, but that most have said they will have it.

I haven't seen this with Telebit, Hayes, and Vadic, and we have a pretty good sample of each. Some off brands, maybe.

Lots of BBS systems and radio amateur links use HST. Most of usenet runs Telebit (for high speed) since that's what uunet uses. The Telebit T2500 supports 1200 and 2400 with MNP, 19.2 with PEP (and uucp support for even higher effective speed), and V.32. I believe v.42 error checking is in the latest ROMs. V.32 is great for interactive use and SL/IP, but on many lines it is useless without error correction of some flavor. The T2500 is about $800 street price, but might have some down a hair recently, there were price drops somewhere. -- bill davidsen - davidsen@sixhub.uucp (uunet!crdgw1!sixhub!davidsen) sysop *IX BBS and Public Access UNIX moderator of comp.binaries.ibm.pc and 80386 mailing list "Stupidity, like virtue, is its own reward" -me
