I have a problem with sdcc 2.2.0 . I have successfully compiled a
x51 project which uses the serial port and which already worked
with an older version of sdcc. The current version is a modified
version which should replace the old one. However it doesn't work.
It compiles successfully and when using the simulator
's51 -s /dev/ttyp1 project.ihx' it prints its startup message
to the serial port as expected. In real live however, it does
nothing at all. The hardware is ok, it's running fine with the
I'm at my wit's end. Can you give me an advice what to do?
