BPQCODE accesses the KISS serial port by directly accessing the hardware and using interrupts, not via any BIOS or OS interface. If your DOS emulator can map hardware I/O on the client side to software access to a COM port on the host side then it should work.
The top 4 bits of the KISS control byte is the channel number on multichannel TNCs. So the displayed frame is either corrupt or is from BPQ configured to use channel 15.

I would like to try to get old BPQ working with DOSFBB. I have DOSFBB
running 100%, but
would like to add NETROM. I have been having issues with getting old
BPQ playing with KISS
TNC's. On a real machine I was able to get the TNC to transmit, but
not receive. On a virtual machine I did not get either TX or RX.
However, I was able to get some error message from direwolf about mal
formed KISS frames.
I could not get BPQ code to work with a real TNC or direwolf, but I
think this info can help:

Invalid transmit channel 15 from KISS client app.
Are you using AX.25 for Linux? It might be trying to use a modified
version of KISS which uses the port (channel) field differently than the
original KISS protocol specification. The solution might be to use
a command like "kissparms -c 1 -p radio" to set CRC none mode.
Another way of doing this is pre-loading the "kiss" kernel module with
CRC disabled:
sudo /sbin/modprobe -q mkiss crc_force=1

Also, I am wondering if BPQCODE needs another COMBIOS type COM port
driver loaded
before running BPQCODE -- that may be the issue as I am running BPQCODE to
bear iron.
