Linux Telnet client
The Linux Telnet client has three anomalies that are known at this time:
A null (\00) character is sent after a carriage return.
If an ALT 255 is entered, two 255 characters are sent (per the Telnet RAFT).
If the code to go back to command mode is entered (ALT 29 which is ^]), the character is
not sent, but Telnet command mode is entered.
