I have a x51 family micro controller (P89V51RD2). I'm going to send some data from computer using serial port. The data i'll be sending are

Character 'S' Character 'R' and a 2 digit integer.

Upon receiving the data, I will be calling separate functions. I used if(chr=='S') and elseif(chr=='R')for character data.

The main problem lies with identifying the 2 digit number sent.

Any other data other than the above three mentioned will be discarded.

Any ideas for identifying two digit integer ??
