hub4com: Framing error stops ports
The virtual serial port driver for Windows.
Brought to you by:

with the following setup
com0com cnca0 cncb0
com0com cbca1 cncb1
hub4com --octs=off --baud=38400 --route=all:all \\.\COM1 \\.\CNCB0 \\.\CNCB1
Physical device on COM1 (autobaud)
Software under test (pyserial app) on cnca0
Hyperterminal on cnca1, used to monitor output only.
If the physical device on COM1 causes a framing error, hub4com reports:
Error COM1: FRAME, total RXOVER=0 OVERRUN=0 RXPARITY=0 FRAME=1
After that no port will respond until hub4com is restarted.

I've tested hub4com. It works correctly after framing errors for me.
So probably there is other reason of the problem.
For example it can be because your physical device begin working for some reason
on other (not 38400) baudrate.
