DCA IRMAkey/3270 issues #781
Description
Hi, I've just got my hands on a DCA IRMAkey/3270. I've ben told that it speaks XT and works with a IBM PC/XT (5160). I've wired up my Teensy with 1k Ohm pull upp resistors and connected the reset cable between Pin 3 on the socket and PB7 on the Teensy.
I'm using the prebuilt .hex-file from GitHub [ibmpc_usb_atmega32u4.hex].
My 122-key terminal IBM Model F & G80-1500 with AT connector works with this setup. But when I connect my IRMAkey I manage to get one key to register and then I get a lot of errors, and after a while I can get another key to register followed by a lot of errors.

This is what I get from "Hid_Listen" when I press the "Q"-key.
I wait for the errors to stop before pressing Q again. Sometimes it types the letter Q and sometimes not.
Device disconnected.
