Yes, it IS a true V.32/V.42bis 9600 baud modem. Where have you been over the last year and a half while the V.32 protocol was being (rather loudly) announced?" Sorry. V.32 is a 2400 baud standard that carries 4 bits per signal, as the previous poster implied. V.32 is 9600 BPS. bps <> baud.

I think that part of the problem is due to the modem manufacturers themselves. For instance, I have a ZOOM 2400 modem that I got a few years ago. I quote from the manual, page 3 (spelling errors are mine; the words are theirs): _General_Description_ This 2400 baud modem provides high speed data communication capability for your computer, terminal or other serial device through an RS-232 serial interface. It is a Digital Signal Procesor based, CCITT V.22 bis compatible modem that supports all the fallback and operating requirements for asynchronous data communications at 2400, 1200, and 300 bps, and it is... So, the company selling me the modem uses the terms baud and bps interchangably - it shouldn't come as a surprise that lots of users are confused about the difference as well.
