Using Telnet › Send Control Codes or Special Characters to the Remote Host

Send Control Codes or Special Characters to the Remote Host

It is likely that you will occasionally need to send control codes such as Ctrl-C, or special characters such as [ to the remote host; for example, Ctrl-D to log off from the host.

The control character is used to do this and it is specified when you start a Telnet connection. The default control character is the cent (¢), but you can change this by using the CTRL operand of the TELNET command.

The control character has the following distinct purposes:

• To simulate the Ctrl key; for example, ¢C becomes Ctrl-C.
• To send characters that are otherwise not supported on 3270 keyboards:

  To send...	Enter...
  [	¢{
  ]	¢}
  Del (X'7F')	¢#
  NUL (X'00')	¢0
  Esc (X'1B')	¢2
  X'1C'-X'1F'	¢3-¢6

Using the ---more--- Prompt

You can send a string of text without the usual Enter character (CRLF or CR) by ending the string with ¢ and the Enter key. For example, you might want to send a single space in response to a --more-- prompt. To do this, press the space bar, type ¢ and press Enter.

Note:  Cisco routers support the command: TERMINAL LENGTH 0, which prevents them from using the --more-- prompt.
