Well, I posted this question to comp.dcom.modems and nobody answered
it. (Am I that much of a dweeb?) But anyway, I was reading the user's
manual to my Databyte Modem 1200 looking at the AT command summary and
ran across the B/B0 command. What exactly does this do? Does someone
I guess the questions should really be Does this run a compression mode
of some sort to increase transmission speeds?
Curious as hell!

My understanding is that the Bell 212 and CCITT V.22 standards are identical except for the initial connect handshake. The B command specifies which handshake to use. If I remember correctly, Bell 212 uses a simple steady tone, while CCITT uses a series of training tones to guage line quality. -- {backbone}!cs.cmu.edu!ralf ARPA: RALF@CS.CMU.EDU FIDO: Ralf Brown 1:129/3.1 BITnet: RALF%CS.CMU.EDU@CMUCCVMA AT&Tnet: (412)268-3053 (school) FAX: ask _How_to_Prove_It_ by Dana Angluin 23. proof by semantic shift: some standard but inconvenient definitions are changed for the statement of the result.
