• Answer:

  A char is one byte. Is the number you're sending more than one byte? If it isn't, you should be able to cast the long/int and send it. (see link) If it is more than one byte, you will need to devise some way to encode it into multiple bytes. A simple way is to send mod(256) the number, then divide by 256 and repeat.
