I'm not sure what the program is trying to do, but I doubt if this is
correct.  /dev/tty0 will usually be a serial line on a Unixy system -
where a terminal, modem or some peripheral is located.  /dev/tty will
be the current login console (keyboard/monitor - may be a window under
a desktop, etc).  I am guessing this code needs to talk to "COM1" on
the PC - in which case there's a whole bunch of coding needed to make
this work.
