I am attaching the packet log of the receiving PC that is giving us the
unexpected parity from host message.  This represents 2 attempts at sending.

Here is the setup file for Kermit:
set port 1
set speed 9600
output AT &F\13
output AT &C1\13
output AT &D2\13
output AT N0\13
output AT s0=1\13
output AT s37=9\13
set parity none
set flow xon/xoff
set handshake none
set duplex full
set warning off
set incomplete discard
set send packet 94
set retry 60
show comm
pause 1

Running Zoom external K56 modems on both ends.

What we are attempting to do is have the calling computer connect to a PC in
server mode.  The calling computer sends a FIN twice which forces the
receiving PC to the beginning of its script.  If the previous calling PC did
not finish its file transfer, the receiving PC may not be in the proper
location and 2 FINs resolve this  The calling PC then sends a file and
issues another FIN, the receiving PC opens that file, sees who this is,
creates a file specific to this caller to send back, the calling computer
then recieves the custom file and then sends its data to the host.  A few
times we have made it into the file transfers but most of the time we just
see what appear to be control characters on the screen then the line seems
to drop.


Any help would be appreciated,
Steve Baus
