I don't know from personal experience, but I'm sure they also support these with V.32 modulation. Certainly, V.42 and V.42bis are standardized by the CCITT for use on V.32, and will also work with the upcoming V.32bis standard (14,400bps modulation, 57,600 throughput with V.42bis). -- Toby ----------------------------------------------------------------------------- Toby Nixon, Principal Engineer Fax: +1-404-441-1213 AT&T: !tnixon Hayes Microcomputer Products Inc.
