[net.micro] NAPLPS protocol

prindle@nadc.arpa (11/20/85)

Could anyone point me to a reference (online or offline) which describes the
NAPLPS terminal protocol - i.e. what escape sequences and control codes cause
what things to happen in the terminal and what unusual sequences the terminal
might send to the host (other than the normal letters, numbers, punct. etc)?
Thank you,

NAPLPS is an ANSI standard, and the best reference is the standard itself,
available from ANSI for about $20.

The basic idea is to use escape sequences to redefine the characters from
(decimal) 32 to 127 (optionally also from 128 to 255 in the 8-bit mode).
The default interpretation for these characters is standard ASCII, but
they can also be defined to be mosaic graphics, redefinable fonts, picture
drawing instructions, or macros.

The stuff the terminal sends back can be fairly complicated, particularly
if unprotected fields are defined (a NAPLPS capability).  Refer to the
Service Reference Model (SRM) appendix in the standard.

If you like, I can send or post the standard number and the address of ANSI.
I have it at home, but not with me.
