Yes, and there is the rub.  My interpretation is that each modem
manufacturer has implemented V.42/V.42bis slightly differently (this
was the gist of a Byte review of these modems) leading to
incompatabilities.  I know for a fact that I cannot do 9600 BPS UUCP
using a Practical Periphials modem to a Telebit T2500 when using
V.42(bis) LAP-M/compression.  If I turn off the V.42/bis stuff the
transfer works OK.

The annoying thing is that you get into a p***ing match where both
modem manufacturers swear that their modem is correct and the other guy
is in the wrong.  In my case there are 6 parties involved:  1)Me,
2)Intel (for the OS), 3)UUNET (for their computer), 4)Telebit,
5)Practical Periperals, and 6)the TELCO.

And numbers 2 throug 6 have been precious little help in getting the
problem solved!
