I have an application that requires very fast handling
of the COM port (RS-232) control lines (like RTS/CTS)
in order to send and retreive characters through the COM port.
To accomplish this, my goal is to use a single board
computer running DOS and a Powerbasic program. (Windows
handling of the COM port is generally not fast enough.)
Is it possible with Powerbasic to switch the control lines
(like switch RTS on and off)? Also, I need to detect when
CTS is high of low.
If this is possible, then can you point me to the
correct section in your manual that discusses these
feature. If it is not, then can you recommend a COM
library that will enhance Powerbasic so that it can
handle these lines?
