Some modems do not react well to parity. Also, if we are dialing through a

negotiations.
This should work even if the user interrupts the DIAL command, because the
DIAL module has its own interrupt handler. BUT... if, for some reason, a
dialing device actually *requires* parity (e.g. CCITT V.25bis says that even

Crude and disgusting, but needed for OS/2, DOS, and Windows, where filenames
have backslashes in them. How do we know if a backslash in a filename is a
directory separator, or if it's a Kermit backslash? This routine does a
rough syntax check of the next few characters and if it looks like it MIGHT
be a variable, then it tries to evaluate it, and if the result is not empty,
we say it's a variable, although sometimes it might not be -- some cases are
truly ambiguous. For example there might a DOS directory called \&a, and
we also have a variable with the same name. This is all for the sake of not
having to tell PC users that they have to double all backslashes in file
and directory names.
Call with a string pointer pointing at the backslash of the suspected
variable. Returns 1 if it seems to be a variable, 0 if not.
