vpix under x11r4 under 386/ix 2.02

I think you are very near to the real problem. I thought, that it should be 
easy, to let vpix run under a normal xterm. If you choose a vt100 emulation,
a IBM-PC compatible fonts (yes there is one available) and hack a file for
the scan-code emulation, everything should be okay. Well, but theres a little
problem: There are two modes for vpix to run: On a terminal or one console.
If it runs on the console, vpix make some ioctl's to /dev/vt??. Some of them
must fail, if an other programm (here our X-server) owns this device already.
This would be no problem, if vpix would recognice, that it runs not on the 
console directly and instead handle the I/O like on a serial terminal.
But vpix recoginces a terminal only, if the calling shell runs on a /dev/tty??.

Perhaps Interactive could give me some hints, how to work aroud this bug...

I think xterm is much better, cause never versions of xterm can now even handle
color.
