I am writing an application where I need to read bytes off a
serial port. No problem so far, but the only I way I know
when to read is if there is a character waiting at the serial
port buffer. Is there a function I can use to check to see
if there is a char waiting to be read at the port?
It looks like select() is what I want, but I cannot figure
out how to use it.
Thanks a lot.
