No way! Most of them should *never* be changed. By the way, some parameters 
may be autodected, e.g. ModemType.

Again, doing so you encourage user to change some setting, that cannot be
changed. Once he/she will change them, and get completely broken system.

BTW, why? Your time is cheaper than the good reliable modem? How much time
have you spent fighting USR? Just multiply this value by your hour rate ...

IMHO wise choice. It's better to use Class1 which is very simple and
error-free for most modems, than try to work around all those buggy
Class2.* firmwares. Also note, that some fax protocol features can be only
implemented using Class1: error-correction mode (ECM), binary file transfer
(BFT), gray-scale mode and many others. The only problem is that you need
*good* Class1 software.

Hope to hear from you soon,
Dmitry
