I have the official serial port add-on for the PC1500 with the user
manual -- somewhere (I know where the unit is, of course). I seem to
remember those keywords were used with it -- COM$ returend the current
RS232 parameters (baud/bits/parity/etc), SETCOM set them, INSTAT and
OUTSTAT were either something to do with the handshake lines or used to
determine if the port was ready (I forget which)

Character input and output was done with PRINT# and INPUT# (I think it
was channel 8 and channel 9 was the centronics port, but it's been many
years).
