The jump_to_isr function is used when the location of the interrupt service
routines are not at the default location in program memory. When an
interrupt occurs, program execution will jump to the default location and
then jump to the specified address.

Requires:
value = kbhit()
value = kbhit (stream)
stream is the stream id assigned to an available RS232 port. If the stream
parameter is not included, the function uses the primary stream used by
getc().
0 (or FALSE) if getc() will need to wait for a character to come in, 1 (or TRUE)
if a character is ready for getc()
If the RS232 is under software control this function returns TRUE if the start
bit of a character is being sent on the RS232 RCV pin. If the RS232 is
hardware this function returns TRUE if a character has been received and is
waiting in the hardware buffer for getc() to read. This function may be used to
poll for data without stopping and waiting for the data to appear. Note that in
the case of software RS232 this function should be called at least 10 times
the bit rate to ensure incoming data is not lost.
