Re: IBM 7855 Modem question

Those are very solid modems as a rule... I would look on the
other end for "noname" modems, that also means "noerrorchecking".

This "sounds" like a "handshake" error when both modems refuse
to negotiate.

The IBM modem will continue to step down speed on crappy
lines but will fold up his tent when the line quality is too poor.
