AT&T UNIX PC Windowing Software (xt/layers)- Version 3.51
AT&T UNIX PC Windowing Software (xt/layers) is a SVR3 feature
included with the AT&T UNIX PC Version 3.51 software. Layers are
asynchronous windows supported by the operating system in a windowing
terminal. Windowing terminals include the AT&T 5620 DMD, AT&T
Teletype 615, and the AT&T Teletype 620. Users should consult terminal
manuals for specific usage.
The AT&T Windowing Software is packaged on an installable floppy
diskette. Software installation follows the normal install procedures (see
AT&T UNIX PC Owner' s Manual, p. 4-55).
The AT&T Windowing Utilities consist of seven commands. A brief
description of these commands and a sample test script follow.
Windowing Utilities Commands
The Windowing Utilities Commands are:
1. ismpx(l) - command reporting whether standard input is connected
to a multiplexed xt channel running layers.
2. jterm(l) - command used to reset a layer of a windowing terminal
after downloading a terminal program that changes the terminal
attributes of the layer.
3. jwin(l) - command that runs only under layers and is used to
determine the size of the layer associated with the current process.
4. layers(l) - manages asynchronous windows on a windowing
terminal, finding an unused xt channel group, and associating it
with the terminal line on its standard output.
5. xtd(lM) - extracts and prints xt driver link structure.
6. xts(lM - extracts and prints xt driver statistics.
7. xtt(lM) - extract and print xt driver packet traces.
Manual pages describing these functions are included with this
documentation.
