Hey Joe, sorry but I'm not sure about your error.
Actually I have a question of my own (not sure how to start a new topic).
I've got hardware plugged into the computer's COM1. I can send data from COM1 to another computer, but I can't send commands from the remote computer to the COM1.
I have virtual ports CNCA0 and CNCB0.
I can use hub4com to send COM1 data to CNCB0.
I can use com2tcp to send CNCB0->CNCA0->remote computer. The remote computer has one virtual pair: COM4 and CNCB0.
If I open COM4 on the remote computer, the data from the 1st computer's COM1 shows up.
However, I cannot send a command back to COM1.
Any ideas?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
If hub4com cannot read from COM5 then try to set properly parameters (default - 19200,8,N,1) for COM5 with options -baud, -data, -parity and -stop.
If above does not help then try with -ix=on option.
If hub4com cannot write to COM5 then try with -octs=off option
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I am setting up the GPS example using COM6 and COM7 and using hub4com route COM5 to CNCB0 and CNCB1. COM5 is a USB port mapped to COM5
I am getting the following error:

Any ideas?

It should not be a reason of the problem.
If hub4com cannot read from COM5 then try to set properly parameters (default - 19200,8,N,1) for COM5 with options -baud, -data, -parity and -stop.
If above does not help then try with -ix=on option.
