I do not use BC++, however the source of your problem may be the fact
that you are trying to use 9600 baud, for polled serial communications.

Using this method the data speed should be limited to 1200 bps.  For
speed greater than this you need to install an interrupt handler to
handle interrupts generated by your serial port.

No.
