- Hello, Udo.
-
- Well, this is normally a question which should be answered by the
- FAQ in the comp.sys.dcomm.modems (or something like that :), but it isn`t
- much you ask so:
-
- V.32 and V.32bis are two of several CCITT communication protocols, in
- our case especially for modems.
-
- Now V.32 is a 9600 baud protocoll (don`t flame me if i got bits/sec and
- baud not correctly :), whereas V.32bis is a 14400 baud protocoll
- (to be exactly, V.32 includes 4 bits per signal and V.32bis 6 bits, and
- the signals are transmittied with 2400 baud, so you get 4*2400=9600 with
- V.32 and 6*2400=14400 with V.32bis).
-
- So your transfer rates and all are quite normal.
-
- Read ya, Phil
