simple xterm?

simple xterm?

[Robert Jordan]

What would be the easiest method for getting a separate VT100 text
window to be created for text_io output?  I'd rather avoid using c calls
(Sun solaris), but if that's the only way to do it, then that's the only
way.

Thanks,

Robert

Assuming a UNIX machine, then simpy determine your tty device
and open "/dev/ttyxxxx" as your filename. In this way, I have
redirected the output of several "subsystems" within a program
to multiple pre-existing xterm devices. You can simply prompt
the user for the device names when the program starts.

In the past, I've kept a list of the desired tty devices
in a separate file which is read by the program. This file
has to be updated each time a new set of xterm's are opened.
With a combination of startup shell scripts and
a wrapper script which opens all the needed xterm's this file
can be automatically setup.

For Windows (and OS/2) it should work to open "COM1", but you have to
take care at transmission speed and dataformat (you can set it at the
DOS-prompt with the MODE-command).

I've not had to do multiple outputs in Windows yet so I have not
given it much tought. How does one send output to more then one
DOS window? In the absence of a better suggestion, I suppose I
can output to artificial files and use cygwin's tail -f command
in each DOS window to scroll the appropriate file as it is
being written.

I think that the best way is to use  Win32  console subsystem.
Using it one may open many console windows for output.
Examples of using it (NT/Win95 Console package ) could
 be found on Jerry van Dijk site " Jerry's Ada on Win32 Page"
