That would be fine. I would run a buffer stage between the keyer IC and the
Epson anyhow. I use a transistor to convert the RS-232 from my PC to the
levels that the Epson keys with now.

Programming with the serial port would work fine.

I suspect the others would like DFCW as well as the QRSS and plain CW if the
chip can do all three. My scheme here is a QRSS-30 and a 15wpm CW message
keying the exciter. So the locals have CW to hear and the DX has QRSS to
see.

Right, you speak  RS232 to the keyer to program it and it keys the TX
with a CMOS 0-5V output.  CMOS outputs being a superset of TTL shouldn't
present much of a problem, right?

Does anyone want anything but this?
