We've been using and experimenting with Hub4com and came to the conclusion that if you use a real com port in it, the real com port won't receive anything from the other loopback ports. Here's our setup:
Loopbacks: COM5<>COM6, COM7<>COM8, COM9<>COM10
c:>hub4com --route=all:all \\.\com1 \\.\com6 \\.\com8
If we issue the above command, com5 and com7 see everything from com1 but com1 doesn't see any input from com5 or com7.
We then tested with the following command using only virtual ports:
c:>hub4com --route=all:all \\.\com6 \\.\com8 \\.\com10
We then used Hyperterminal to test and everything worked as expected. All ports could receive data from any other port.
Is there some trick to getting a physical com port (COM1) to accept data with hub4com?
