It looks like you are using Device::SerialPort as your serial port management module. Please correct me if that's wrong. That kind of information can really be helpful in diagnosing your problem.

Does the device to which you're sending data handle rts/cts signals? If so, get it to send you a clear-to-send and send a character only once that's received. Lowering your baud rate to something that guarantees your characters don't go faster may help, too.
