When using the null modem cable on the FreeBSD machine to another computer terminal, I receive the login prompt when the null modem cable is connected, and when I login, and then disconnect the cable and reconnect the cable again I receive the login prompt again. It appears the getty process in FreeBSD is detecting the carrier loss when the cable is disconnected and ending the previous login session. This is the correct behaviour to my understanding.
However on the Solaris system, when the null modem cable is connected to another computer terminal, if I login, and then disconnect the cable and then connect it back again I am still logged in at the shell. This means that on the Solaris machine it did not detect the carrier loss when the null modem cable was disconnected.
Since I have tried the same null modem cable on both the FreeBSD machine and the Solaris machine, I am thinking it has something to do with either a configuration setting in Solaris itself, the hardware on which Solaris is running on, or something else? ....

NAME
Device::Modem::UsRobotics - USR modems extensions to control self-mode
SYNOPSIS
use Device::Modem::UsRobotics;
my $modem = new Device::Modem::UsRobotics( port => '/dev/ttyS1' );
$modem->connect( baudrate => 9600 );
my %info = $modem->messages_info();
print "There are $info{unreleased_voice_msg} unread voice messages on $info{stored_voice_msg} total
";
print "There are $info{unreleased_fax_msg} unread fax messages on $info{stored_fax_msg} total
";
# Get details about message n. X
my %msg = $modem->message_info(1);
index type information attributes status day hour minute
callerid page addresshigh addresslow checksum
print 'This is a ', ($msg{type} == 2 ? 'voice' : 'fax'), 'message', "
";
print 'It came from no. ', $msg{callerid}, "
";
# ...
# Now clear all messages
$modem->clear_memory();
WARNING
This module is not documented yet, and it is a rough work in progress. Until now, it correctly reads voice/fax messages information, but
when saving voice messages to disk, sometimes they are incorrectly decoded.
So, if you need a working program, check out the good old TkUsr by Ludovic Drolez, unless you want to help develop
Device::Modem::UsRobotics.
DOCS TO BE COMPLETED FROM NOW.....
Yes, I'm a bad boy :-)
DESCRIPTION
Bla Bla Bla...
METHODS
clear_memory()
Used to permanently clear the memory space of the modem. There are separate memory spaces, one for voice/fax messages and one for user set-
tings. Examples:
$modem->clear_memory('user'); # or $modem->clear_memory(1)
$modem->clear_memory('messages'); # or $modem->clear_memory(2)
To clear both, you can use:
$modem->clear_memory('all'); # or $modem->clear_memory(0);
Parameters:
$memtype
String or integer that selects the type of memory to be cleared, where 0 is for "all", 1 is for "user" memory, 2 is for "messages" mem-
ory.
