in reply to baudrate issue with script

motoprog:

It looks like the Device::SerialPort->new("/dev/ttyS0"); statement isn't returning a serial port for you. You should check things like that in your code. For example:

my $port = Device::SerialPort->new("/dev/ttyS0"); die "Can't open /dev/ttyS0: $!" if ! defined $port;

Please note: Your code may not have enough permissions to open the serial port. For some versions of *nix, you may not even have a /dev/ttyS0!

When your only tool is a hammer, all problems look like your thumb.
