Since I have received several messages about my GVC download problem,
and have seen several posted, I thought I'd better clear up a few things,
and relay some more info.

To ensure everybody is singing from the same songbook, I have repeated my
original message along with added emphasis to some points that
weren't clear, judging by the responses:

****************************************************************************

^I just purchased a GVC 9600 V.42 modem from CompuAdd ($429), and it
^works great with Procomm Plus 1.1B except for one thing.  When logged
^into B at 2400,e,7,1 (the only settings I can use in my area),
^I can't download files.  I have tried xmodem, cis quick-b, and kermit,
^                                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
^all to no avail.  Xmodem receives the CRC signal from CIS, and tries to
^send its OK message, but the two sides never get synchronized, and
^eventually a "time out" message is received.  The same symptoms occur
^for the other protocols.
^
^I've tried dialing the university with the same settings, and both
^kermit and zmodem work fine, regardless of the baud and parity
^parameters.  Surprisingly enough, the MS Windows 3.0 terminal program
^works fine, but setting PCPLUS as close as I can to the win-terminal
^program doesn't help.
^
^Surely there is a simple setting the new modem has that the old one
^didn't (a Packard Bell 2400Plus [OEM'ed by GVC]).  The ONLY variable
^                                                   ^^^^^^^^^^^^^^^^^
^that has changed is the modem.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
^Other than this annoying problem, I am very pleased with the GVC
^modem.  I have been much too slow in getting a 9600 baud modem for
^home.

Additional comments:

--With my old Packard Bell 2400 baud modem, I NEVER HAD ANY TROUBLE USING
  ANY OF THE PROTOCOLS AVAILABLE ON COMPUSERVE, WITH 2400,E,7,1, PERIOD.

--I am calling a CIS port direct, with a local number.

--I used XMODEM in the original posting as an example because I got the
  best error messages from it when it bombed.  I normally use CIS Quick-B
  as my protocol of choice on CompuServe.

--Yes, the kermit option in win3's  terminal.exe  works!  But that is
  not my terminal program of choice!

--The university has different dial-up phone numbers (one is autobaud
  adjusting for 300/1200/2400, and the other number is capable of
  300/1200/9600).  Both work as they should the with 9600 baud modem.

--I have since tried some other programs, to try to track down the
  problem.  I found that TELIX 3.15 exhibits the same problem with
  CompuServe that PCPLUS 1.1B does, using any of the three mentioned
  protocols. MS-KERMIT 3.10 works fine with kermit on CompuServe.

--Another interesting fact I discovered when using Telix is that judging
  by the message returned by the modem, namely "CONNECT 2400 REL", the
  modem on CompuServe's end is using MNP-5.  However, when I disable the
  MNP-5 on my modem, and get the corresponding message from my modem
  "CONNECT 2400", indicating a data only connection, I still can't
  download, though everything else works as it should.

Thanks for the many responses.  I we ever discover the problem, (and it
is not posted), I will spread the word.
