hi
about DEC lk201 for DEC Terminal vt220,
I am looking for information about
- the pinout of the connector (it should be 4 pins, sort of serial)
- the protocol used
- key keymap
There is extensive documentation around. If you look at Linux's
lkkbd.c[1], you'll find the pinout, how to build an adaptor to use it
on a regular serial port and a pointer to some scanned PDF[2] where
the hardware and protocol is descriped in depth.
