[snip c code]
Above is my serial code for Linux, and I am having a problem in which I
sometimes get a sloppy serial read from the other devices on my robot
(and even when testing in hyperterminal). For instance, I will expect
to receive a 'd' serially about 30 times and only receive it accurately
about 20 of them. I will receive another character instead the other 10
times. Is there a flush command that I have to perform to clear the
buffer before each read. I am sending one character and receiving one
character at a time, and I am never expecting to receive two characters
at the same time, so performing a flush all would not hurt my
functionality. I am familiar with the TCSAFLUSH (I believe that is what
it is called), but does this need to be performed often? What could be
causing me to get these seemingly random sloppy reads?
Perhaps you need flow control.
