Back in college in the HP lab we had these really nice RS232 breakout boxes with jumper pins and LEDs that were in a sort of pink case. While I used them all the time I can no longer remember who made them or find anything close.

The manual says that it uses DTR for flow control and doesn’t mention DSR, so I suspect it’s a one-way thing like the HP terminals and only tells the other end to stop and will send whenever it wants without checking if it’s ok.
