Hi
I've recently written a Hackmaster hack to perform background tasks and I
now want to read some data from the serial port in the short period of time
that I do my background processing.
I thought that I could just do a :
SerOpen();
SerCheckReceive();
if (data) {
bla bla
}
SerClose();
For some reason I never read in any data although my code works (tested it
in a normal 'application'). I always receive 0 (zero) bytes from the
SerCheckReceive function. Is the same by the way even if you use the New
Serial Manager functions. Does SerOpen() flush out the receive port? Is
there a better way to quickly nip in, read data from the serial port and nip
out again? I emphasize that this is a background task, so I can't just open
the serial port when the application starts and then close it when it shuts
down. I have to do any initialisation every time my trap handler gets
called.
Any thoughts on this appreciated. No more late nights please swearing at the
computer!
