Subject: TeleVideo Terminal control codes needed

In response to your message sent  05/17/81 04:30:38

There are now, to my understanding five versions of terminals marketed by
TeleVideo, Inc.  The 912B and 912C differ only in keyboard arrangement (the
912B has an 84 key keyboard comprised of alphanumeric characters, symbols,
and control keys to perform its full operations; the 912C has an 82 key
keyboard, in a standard typewriter style, with alphanumeric characters,
symbols, and control keys).  The 920B and 920C are similar to the 912x
series except that 11 special function keys have been added.  All four
models can produce the standard full 128 ASCII character set and can be
optionally (read more $, about $25) be configured with a second display
page.  Upper/lower case display with descenders is standard.  There is a 
new 950 model about which I know zilch.

For the control codes, note that a Televideo is almost identical to a Soroc
IQ 120 terminal.  For a lot of CP/M programs which tailor to terminal codes,
settings for Soroc IQ 120s works quite well.

Quote page 31 of the TeleVideo Operator's Reference Handbook (the same manual
regardless of TVI 912B-C/920B-C tube):
