Telnet.pm question regarding buffer size

[Scott Clay]

#!/usr/bin/perl

use Net::Telnet();
use Net::FTP;

$telnetObj->cmd("ll 12345678901234567890123456789012345678"); //works

## The above command works fine passing it to a second linux box (41 chars
all together) . However, the command below (42 chars) errors out. I think it
has to do with ## the strings length. Is there anyway to increase the buffer
size that I need to pass the string?

$telnetObj->cmd("ll 123456789012345678901234567890123456789"); //DOESN'T
Work


Input.txt File From the Telnet Object (Longer Command I'm trying to pass on
the 2nd machine):

So what does it do? Show the error message!

That looks pretty chaotic, at least after Usenet has had its way with it.

In any case, a buffer of 40 bytes size is pretty unlikely. The problem
is probably something else.
