! Use an explicit path (eg /dev/ttyS1) or send this information to
! the author of this module:
sys.platform = %r
os.name = %r
serialposix.py version = %s
also add the device name of the serial port and where the
counting starts for the first serial port.
e.g. 'first serial port: /dev/ttyS0'
and with a bit luck you can get this module running...
