Description:
------------
I am using sockets to log in to a Cisco router. I need to issues the command "terminal length 0". The 0 must return a FALSE or NULL status to socket_write or maybe socket_read is what is actually returning false I am not sure. But it will not work in Binary, ASCII, OCTAL, HEX anything.

 

Reproduce code:
---------------
$IosCmdExec = 'terminal length 0' . "\n";
socket_write($socket, $IosCmdExec, strlen($IosCmdExec)); 

$makeCaptureFile = 'C:\rtrconfig\config.txt';
$captureFile = fopen($makeCaptureFile,'a');
$out = '';

while ($out = socket_read($socket, 1024)){ 
ereg_replace("\r", ' ', $out);
fwrite($captureFile, $out);
}

$sep = '***************************************************************************************';		
fwrite($captureFile, $sep);	

socket_shutdown($socket, 2);
socket_close($socket); 

Expected result:
----------------
I expect the writing of 'terminal length 0' to the Cisco CLI. It works fine as long as the digit is not 0. 1-512 etc.

xxxxxx#terminal length 512
