Dear Monks,

First post here. Pretty new to Perl as well, been working with it for about 6 months.

I am using the Net::Telnet module in some of my code. Running on Wintel, Active State V5.8.8.

I am using Net::Telnet with the error mode set to 'return'. When an error occurs, I check the errmsg string. More often than not, I get something like this 'read error: Unknown error'. Not terribly helpful. I Googled around and read through the docs but I am wondering if there is any more information that I can obtain about the nature of the error (such as maybe the winsock error code).

I have considered setting the error mode to 'die' and then just wrapping the code in an eval block but that's less than ideal in the environment I am in.

Thanks in advance for your help!

-Adam Update: 

$self->{logger}->info("Running cmd on device $self->{device}: '$cmd'")
+;
$self->ethtelnet()->buffer_empty();

my @lines  = $self->ethtelnet()->cmd(String => $cmd, Timeout => $timeo
+ut,
                                     Errmode => 'return');
my $error  = $self->ethtelnet()->errmsg();
my $buffer = ${$self->ethtelnet()->buffer()};

if($error)
{
    undef($self->{ethtelnet});
    $self->ConnectConsole();
    die "Telnet error attempting to issue command '$cmd' to eth port,
         error:\n$error\nbuffer:\n$buffer";
}

When this code runs I get the following output in the failure case: Test line: 35 Telnet error attempting to issue command 'my_command -j' to eth port, error: read error: Unknown error buffer:
