The breakout box is an old troubleshooting tool. Its basically some LED's across all the lines. If you turn off hardware flow control (or jumper the flow control lines) you can then watch the LED's flash as you send out data.

I'm testing with my old HP48SX calculator. Installed C-kermit on Linux and can successfully send files to/from the calculator. I remembered back in 1992 when I first bought it I would have used my Amiga so I've been looking through the early fish disks and found a couple Kermit programs and a couple terminal programs to see if I can get it working again.

So no blinkin lights from date >ser:

I wonder if the serial prefs are not ignoring flow control, I'll try jumpering those and see
