And, more than one different model!

A bunch of yuears ago, Joe Campbell ("C Programmer's Guide To Serialo 
Communication", "RS232 Solution", etc, NOT the PBS Joe Campbell) told me 
that he was doing some consulting for Hayes, about setting up the standard 
for "Hayes Compatible"; it seemed that not all of their modems did things 
the same way!   I don't know WHICH things needed to be adjusted.
