Description
In version 3.1.3 once connected to Cisco Switches in SSHShellStream running "terminal length 0" with bellow commands to display multiple lines was working fine.
Since 3.2.3 same commands are failing to generate any output.
$shellStream = New-SSHShellStream -SessionId $SessionID.SessionId
$shellStream.WriteLine("terminal length 0")
$shellStream.WriteLine("show interfaces status | include disabled.* 99 ")
I was able to force to import version 3.1.3 as a workaround.

Research direction
Start with the New-SSHShellStream entry point and reproduce the issue against the reported 3.2.3 and 3.1.3 versions using the two Cisco commands in the report. Compare the shell stream behavior and determine why terminal length 0 suppresses subsequent output; done means the commands again return their expected output in the affected version.
