ScriptingTelnet

Question

i have a class for telneting in to a system which ok but i found one here by

Telnet Scripting in C# by Tyler Kline which works even better but i am trying to get a telnet seasion to

send multible commands to the telnet seasion like
Login before i can send admin commands
send(login user pw)
once logged in now send admin commands
send(adminsendmsg msg )

with both tylers and my class it never seems to take the second command
was woundering if someone has a sameple of doing this with tylers class or another option for me to do this?
