I'm able to use a proprietary application to talk to some proprietary hardware using com2tcp when both the com2tcp 'server' and 'client' are running on the same computer.
When I try to move the client to a remote computer the proprietary application gives me a timeout message and has no settings to increase the timeout.
I used this command for the server, where com1 is the physical port with the hardware attached.
I used this command for the client, where com10 and 11 are a com0com pair
com2tcp --telnet --ignore-dsr -baud 57600 \\.\com10 192.168.7.102 3141
As I said, com11 works fine from 192.168.7.102 but when I try with a computer that is on a remote network (300ms pings) the application gives timeouts. I don't know anything about the serial protocol the application and hardware are using.
Does anyone have any suggestions as to how I can get this to work (or debug further?)
Thanks for your help & great project

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
1) Did you tried to set EmuBR=yes for com0com ports?
2) I plan to implement com0com parameters that will
allow to add some values to read timeouts (it will
helpful only if application use ones).

With com0com from CVS you can try to fix the problem by
ajusting AddRTTO and AddRITO params for com11.
AddRTTO=<n> - add <n> milliseconds to the total time-out period
for read operations (0 by default)
AddRITO=<n> - add <n> milliseconds to the maximum time allowed to
elapse between the arrival of two characters for
read operations (0 by default)
