There is a standard which consists of an enhancement to the famous Hayes
AT command set for modems. There are different classes defined, but only
the lower ones are already fixed. The main drawback is that you normally
have to use an RS232 interface at 19200 bps which is quite a heavy interrupt
load for the PC.
Additionally there is the DCA/Intel CAS standard (currently version 1.2) which
becomes more and more used by software developers. Especially the new
Intel SatisFAXtion board with its excellent price/performance ratio will
lead to even more applications. The documentation and a programmers
toolkit is available at INTEL PCEO. There are two drawbacks:
- no official commitee is discussing this standard (as to my knowledge)
- the method of file-transfer is not documented and is also ancient, because
it does not use error correction mode
