 Escape key timing issue and terminal function keys OSR5
I have a customer with some old DG terminals.  The <F1> key and <F8> key
in his application behaves erratically with ragards to ACCUCOBOL.  
Because the keys sometimes works and sometimes does not work, my
thought is that this is a timing issue in regards to the system's
recognition of a sequence of keys being a single keystroke and it
being individual keys.

I thought there was a way to change the timing used in determining
this.  I need to change this behavior in OSR5 Enterprise.  There
appears to be no itool script that applies.

In the curses library under Xenix, the timeout value was around zero. In
the SCO 4.2 Unix one, the timeout was 1 sec. (It can be changed with adb.)
So, if the application is using curses, the value is hard coded. If it
isn't, all bets are off. Lotus, for example, has an environment variable
which changes the function key sequence timeout. If ACCUCOBOL doesn't
have a similar feature, you will probably have to ask them for one.

This sort of problem usually happens over TCP connections and modems, not
on direct terminal connections. With ancient terminals, lowering the baud
rate may fix it, as the function key sequence detection may rely on line
speed for its delay, and may therefore expect a longer delay at lower
