This directory contains the source for the TTY interface, a device independent
interface used to control terminals. We interface to the widely used
TERMCAP terminal database, thereby gaining the data required to control many
diverse terminals. (Written Jan84 dct).
Mar84 Added TTYGDES and the "graphcap" file, used to describe graphics
devices.
Jly84 Added capability to compile selected termcap entries to speedup
TTYODES. Added TTYCOMPILE, TTYLOAD, TTYOPEN, TTYCLOSE. Modified
the existing routines TTYODES and TTYGDES. The new open and close
routines are useful for any type of database maintained in termcap
format.
Jly84 Entry point TTYCLINE changed to TTYCLEARLN to avoid name conflict
with TTYCLOSE.
Jly84 Task MKTTYDATA is used to compile selected entries from TERMCAP
files. The include files "cache_?.dat" are the output of this
program. To tailor the cache of pre-compiled termcap device
entries for a site, compile MKTTYDATA and run it to generate
the files "cache_t.dat" for "dev$termcap" (default MKTTYDATA params)
and "cache_g.dat" for "dev$graphcap", then do a Sysgen to recompile
the libraries. All programs which use the TTY interface, e.g.,
the SYSTEM package, must then be relinked to make use of the new
cache.
Jun85 Changed filenames to make them more machine independent.
Installed MKTTYDATA as a task in the SOFTOOLS package.
