Notes on Specific Telnet Clients
Telnet and terminal clients will have different behaviors in some situations. This section states some of the known
anomalies.
Windows Client Programs
Anomalies occur when using a Windows™ client if you are not typing standard ASCII characters (i.e. using the keypad
and the ALT key to enter decimal codes). Most programs will allow you to enter specific decimal codes by holding ALT
and using keypad numbers.
For example, hold ALT, hit the keypad 1, then hit keypad 0, then release ALT. The standard line feed code is entered
(decimal 10). Windows will perform an ANSI to OEM conversion on some codes entered this way because of the way
Windows handles languages and code pages.
The following codes are known to be altered, but others may be affected depending on the computer's setup.
Characters 15 , 21 , 22 , and any characters above 127 .
This affects both Windows Telnet and Terminal programs.
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.
Enabling/Disabling Telnet on the Keypad
By default, Telnet is enabled on all Metreau keypads. The default Telnet port is 23 .
You can change the Telnet port by using the SET TELNET PORT command (see page 27). Setting the Telnet port to zero
disables Telnet access.
The SET TELNET PORT command requires a reboot to enable new settings.
Note: The only way to re-enable Telnet once it has been disabled is to reset the unit to the factory default firmware
image. See the Simulating the ID Pushbutton section on page 9 for details.
