Declarent has asked for the wisdom of the Perl Monks concerning the following question:

Okay, I want to dial a modem. Pretty simple. Here's my code: 
#!/usr/local/bin/perl

# Modem test

use Device::SerialPort;
$PortName="/dev/ttyS1";
$modem=new Device::SerialPort ($PortName);

print "Modem Test...\n";


$modem->error_msg(ON);

$modem->baudrate(115200);
$modem->parity("none");
$modem->databits(8);
$modem->stopbits(1);

$modem->are_match("BUSY","CONNECT","OK","NO DIALTONE","ERROR","RING",
                     "NO CARRIER","NO ANSWER");

#$modem->write("ATZ\r") || die "Could Not Reset\n";


$number="8885555555";

$modem->read_const_time(30000);


$modem->write("ATDT$number\n\r") || die "Could Not Dial\n";
sleep 5;

$modem->write("ATH\r") || die "Could Not Dial\n";

Upon running it, I get this:

Device::Serial could not find ioctl definitions! disabling ioctl methods - constants not found

Ugh. This is Redhat 7.3. I've already run h2ph, and I do have asm/termios.ph. Anyone have any ideas? Or even better, some reliable way that I can send stuff to the modem without this module? BTW, notice that I don't ever read from the serial port, I just need to dial the number, send a string, and hang up.

As always, thanks.
