Hi, I am sure that answer to this problem is simple. What I am trying to do is to communicate over serial port using Device::SerialPort. The problem is when I am trying to send long string. Only a part of it is transmitted. I understand that buffer has limits. I can do it while openning file and sending data from file using while <file >, but for string?? Here is an example of my code ( numbers up to 8 are sent, nothing after that:

a
#!/usr/bin/perl
use strict;
use warnings;
use Device::SerialPort;

my $PORT = "/dev/ttyO1";

my $ob = Device::SerialPort->new($PORT) || die "Can't Open $PORT: $!";

$ob->baudrate(115200) || die "failed setting baudrate";
$ob->parity("none") || die "failed setting parity";
$ob->databits(8) || die "failed setting databits";
$ob->handshake("none") || die "failed setting handshake";
$ob->write_settings || die "no settings";
$| = 1;

my $string  = "1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20\n";
$ob->write( "$string\n");

Any idea how to fix it?? Thanks in advance. Robert
