- It looks to me like you sacrifice some flexibility in what you can
- send to the modem (ie: your CPU does a little more of the work), but
- you don't sacrifice any capabilities. Intel FAX modems run a
- high level protocol called CAS. Their co-processed FAX modems run
- CAS internally, but their new external 400/e uses a CAS software
- driver for the Class I command set. It has all the same features
- as the sophisticated co-processed versions.
-
- In other words, the only people that suffer from Class I are
- software developers producing FAX software.
