This is a simple example of how to control a serial port using perl in linux.
For WIN32 systems please check out the Win32::Serial module.

| #!/usr/bin/perl
use Device::SerialPort;
my $port = Device::SerialPort->new("/dev/ttyUSB0");
$port->databits(8);
$port->baudrate(19200);
$port->parity("none");
$port->stopbits(1);
while(1) {
my $byte=$port->read(1);
print "$byte";
} |
Nice! This is the first example that I’ve tried that actually worked! The main difference is that most sites have you use
my $byte = $port->lookfor(); #Which does not work!!!
my $byte = $port->read(1); #works!!!
Thanks!
