Hello Janusz,
I thought you got this working a long time ago. No? I know you had changed the PCI card out once but I think the new card still used the same serial chip. Correct? If so, you need to see if you can find a serial card with a DIFFERENT serial chip. If you never did get it working with either card, I would suspect the PCI serial card not being fully 16550 compatible. It's a known fact that those old serial-attach Baycom modems do unique things with the serial port signalling to make the TNC work. I also have noticed that the BayCom website has been stripped of all it's content.
To confirm, the serial card you have is this one:
