I have never seen QTerm, but Kermit-80 v4.11 does have a Microbee version.

Get a Microbee technical manual.

The microbee serial port is 4 bits of the PIO - TX, RX, CTS and one 
other non-standard one.  The other PIO bits are used for tape in, 
tape out, tape on/off, speaker.  Programming serial routines is a real pain.
Input is interrupt driven so that you don't lose characters when the 
keyboard is being scanned or the video screen scrolled.
