I stand corrected. I keep a VT420 on my desk with an LK421 (the "Unix"
keyboard), connected to my workstation (now via a USB serial adapter). I
just popped the keyboard and it is, indeed, an RJ11 for the keyboard.
Serial is MMJ, which connects to an MMJ<->DB9 converter which connects to a
mini null-modem to the USB adapter. So simple.
