possible bug found: 00 byte unwanted

[gabrago]

Hello all,
I have created two  virtual pairs  COM177<->CNCB0 and COM178<->CNCB1 .
I have added this line in multilpexer.bat after line 48 :     IF /I "%OPTION%" == "-octs"   GOTO BEGIN_OPTION_LC
Then I do: multiplexer.bat -trace -octs=off COM177 CNCB1,
finally I open with putty.exe a terminal to COM178 and type the letter "a" (that is 61 in hex"),
then COM177 receive ""00 61", and this happens for all bytes that I send from COM178, id est there is always an unwanted "00" prepended,
can anyone help me?

This is the otput of the command:
…….

Are you sure you need multilpexer?
If you multilpex data then you need demultilpex it on the other end.

Really I would share a phoenix reader with a sim card inside, but I don't know if it is possible,
thank you anyway for com0com, I think it will be useful.
