Hi all,
I am trying to communicate to one machine through serial port ( COM port )
sau /etc/ttyS0. I am making use of serialPort.pm for this. The script is
able to open the connection using new() method but after that nothing comes
up . I want who lot of boot up messages to come on console. I am getting all
these messages when i use minicom cli modem. This is the script i am using.
Please help me . this is very urgent.

use strict;
use vars qw( $OS_win $ob $port );
BEGIN {
$OS_win = ($^O eq "MSWin32") ? 1 : 0;
if ($OS_win) {
eval "use Win32::SerialPort 0.11";
die "$@\n" if ($@);
}
else {
eval "use Device::SerialPort";
die "$@\n" if ($@);
}
} # End BEGIN
$file = "test.cfg";
if ($OS_win) {
$ob = Win32::SerialPort->start ($file);
}
else {
$port = '/dev/ttyS0';
$ob = Device::SerialPort->new ($port);
}
die "Can't open serial port from $file: $^E\n" unless ($ob);
my $baud = $ob->baudrate(9600);
my $parity = $ob->parity('none');
my $data = $ob->databits(8);
my $stop = $ob->stopbits(1);
print "B = $baud, D = $data, S = $stop, P = $parity\n";
while(1)
{
($count, $result) = $ob->read(10);
print $result;
}
undef $ob;
This program just prints few lines of the boot log. Can anybody points me to
the mistake. I would highly appreciate a quick response. This is kind of
urgent. If somebosy have some sample programs , pls send them to me.
Regards,
Sushil
