I've seen some modems that, while they pass data at 1200 (or 2400) bps, are
not able to accept a command line burst at full rated speed. Are you able to
send a dialing string a character at a time, from the keyboard, and not able to
autodial from a program's phonebook?
Also, what happens with some of the other commands? Does ATH1 or ATA pick up
the line?
