  Notice in my first post that I *do* ask wether MiNT itself or
the shell is the one supposed to support this. Also, while TCSH
has an extensive (maybe even excessive?) MAN page, BASH doesn't
provide much in term of docs or shell feature, if the manual is
any indication.

  As I read further in this Unix book, I see that $LOGTTY or $TTY
provide the same result: the device name on which we're loged in. 
I assume one would be Bourne syntax and the other CSH syntax, but
neither work here on MiNT, hence why I asked this list, since all
the Linux/BSD/whatchamacallitunixthang users I ask, about finding
which device is used through an environment string, suggest $TTY.
Then, when it doesn't work they're all amazed, cause it works on
all Unix variants they have running on their various machines...
