Subject: mex comm. utility (cpm)

    I have been using a public domain communications program called
    MEX.  I have it configured for an Otrona Attache.  My problem is
    that MEX seems to be eating the <esc> character, thus defeating
    the terminal emulation capabilities of the Attache.

    Question:  Does anyone know of a patch to fix this problem.

The problem is easily fixed.  In all the user overlays for MEX and
MODEM7 there is an equate that sets whether control characters are
passed along to the console in the terminal mode.  Look for this:

IGNCTL: DB      NO              ;yes=do not send control characters
                                ;above CTL-M to CRT in terminal mode
                                ;no=send any incoming CTL-char to CRT

Chances are yours is set to YES instead of NO.
