- Remember that regular modem communication is full duplex, and FAX is
- uni-directional.
-
- My understanding is that a 2400 baud modem splits the available (6khz ?)
- bandwidth into an upper and a lower band. The originator of the call
- uses the lower, the answerer uses the upper, or vice versa.
-
- FAX, on the other hand, does 'talk talk' OVER 'talk talk' OVER.
-
- Thus it can use the whole band. Thus a 9600 FAX has the same technology
- as 2400 data.

- Cheers, Andy.
