Calling user data
The calling user data field for a normal call can contain up to 12 bytes of user data. If the first
character is an exclamation mark (!), the PAD omits the 4-byte protocol identifier, and allows the
full 16 bytes as user data. The same is true for a fast select call, except the maximum amount of
user data is increased from 124 to 128 bytes. When entering user data, you can use the tilde
character () to toggle between ASCII and binary mode. In ASCII mode, data is accepted as
typed, but in binary mode, you must enter each byte as the required decimal ASCII code
separated by commas. For example, to enter the data Line1 followed by [CR][LF] and Line2,
enter:
DLine1~13,10~Line2
CLR command: Abort a CALL command
To abort an X.25 CALL, use the X.28 CLR command, do one of the following:
Press [Enter].
▪
Drop DTR from the terminal while the call is in progress. Dropping DTR will also terminate an
▪
established call.
If a call is terminated by the network or by the remote host, the router returns a diagnostic message
before the NO CARRIER result code. Messages can be numeric or verbose, depending on the setting
of the ATV command.
