How to detect terminal type?

[Peter Brinkmann]

Hi!
How can I detect the current terminal type?
I'm asking because I sometimes need to change the terminal type
in order to export plots to encapsulated PostScript, using a
command like
        gset terminal postscript
On my Linux box, I can reset the terminal with a command like
        gset terminal x11
The problem is that this doesn't work under Windows. So, what
I'd like to do is the following:
        1. Detect and remember the current terminal type.
        2. Export stuff to PostScript.
        3. Reset the terminal type to what it was before.
Is this possible at all?
Thanks,
        Peter
