(81) FETCH X.21
CONFIGURATION
The FETCH X.21 CONFIGURATION request and response are used to retrieve the
current values of the X.21 configuration block in the LIU.
Request The FETCH X.21 CONFIGURATION request retrieves the current values for X.21
configuration parameters. For information about the parameters, see“X.21 Line
Configuration Options” in Section 3, “ADCCP/X21 Protocol Module”.
The request buffer format is:
Function := 81
Modifier := 0
Request ID := A unique value from 1 to 32767,
determined by the application
Text Out := 0
Text In := 34
Response The FETCH X.21 CONFIGURATION response is the expected answer to the FETCH
X.21 CONFIGURATION request. The format of this response depends on whether the
request completes successfully.
If no error occurs, the FETCH CONFIGURATION response contains a copy of the X.21
configuration block stored in the LIU.
The response buffer format is:
Response := 81
Status := 0
Request ID := The same as in the request
Text Out := 0
Text In := 34
Text := CIRCUIT-SWITCHED :Byte
NOT READY STATE :Byte
