DEC VT420 serial terminal
I've connected a VT420 terminal to my Ubuntu box. It works, as a VT100/VT102 (easy for me, electronics engineer), but...(isn't there always a 'but'?)
How would I configure this one terminal (the PC has 2 serial ports but only one 'brought out' off the motherboard to the back) to be able to use VT420 features, eg 132 column/48 rows (yes, my eyesight is acute...)? I'm happy to make a 'special' login name for this, but am confused about which files I need to modify. I'm running Ubuntu 9.10, so it uses /etc/event.d/vt220 etc instead of terminfo, the docs I've seen almost invariable refer to the latter, hence my confusion. I'm dead sure this must be simple, but so am I, it seems.
Thanks for any help.
