SERIAL PORT
Post by wyzeowl on Apr 6th, 2013, 12:29pm

I have the need to clear the serial port buffer after every read. I believe that there used to be an OSbyte command to do this. Is ther anything I can do.
Thankyou

The most straightforward way is probably to read (and discard) bytes until the buffer is empty:

Code:
     WHILE EXT#com% junk% = BGET#com% : ENDWHILE
