Hi all. I’m trying to write a program that will store three characters from the serial port, and store them in szBuffer.
All is well, but i have a small problem i don’t know how to fix
Well there are a total number of input characters that aren’t a integer multple of 3, then i will have remaining characters lingering in my buffer.
How do i get rid of these values, as they screw up programs inputs the next time the program is run.
iBytesRead = readcond(iFileDescriptor, szBufferI,3,3,0,0);
szBufferI[iBytesRead] = ‘\0’;
