* probably very mistaken. There be serious and nasty dragons here.

|
|
* This client is *not* to be taken as an example of how to write X
|
|
* Toolkit applications. It is in need of a substantial rewrite,
|
|
* ideally to create a generic tty widget with several different parsing
|
|
* widgets so that you can plug 'em together any way you want. Don't
|
|
* hold your breath, though....

program on 80386/80486 in v86 mode. In other words, you can spawn
|
|
off multiple MS-DOS environments. On ISC the program that does
|
|
this is named "vpix." The catcher is that "vpix" will *not* work
|
|
with a /dev/pts??? device, will only work with a /dev/ttyp? device.
|
|
|
|
Since we can open either a /dev/ttyp? or a /dev/pts??? device,
|
|
the flag "IsPts" is set here so that we know which type of
|
|
device we're dealing with in routine spawnXTerm(). That's the reason
|
|
for the "if (IsPts)" statement in spawnXTerm(); we have two different
|
|
device types which need to be handled differently.
