WRITING APPLICATIONS THAT USE 6100 MPS-B
FETCH CONFIGURATION Request
FETCH CONFIGURATION Request
The FETCH CONFIGURATION request retrieves the current values of
the line configuration parameters (as stored in the LIU). For
information about the standard parameters, see "Line
Configuration Options" in Section 1; the names that appear in
the list below are the names you use in the SYSGEN entry.
This request can be issued at any time, and does not affect the
line state. Notice that although the Text In value is ignored,
the read count in the WRITEREAD request must be large enough for
the data being read, plus 8 bytes for the rest of the response
buffer.
The request buffer format is:
Function := 2
Modifier := 0
Request ID := A unique value from 1 to 32767,
application-dependent
Text Out := Doesn’t matter
Text In := 26 to return the standard line configuration
block
46 to return the extended line configuration
block
Text := Doesn’t matter
The response buffer format is:
Function := 2
Status := 0 if the operation completed successfully, or
a code greater than zero if an error occurred
Request ID := The same as in the request
Text Out := 0
Text In := Length of line configuration data block, or
2 if status detail code is present in Text field
Text := line configuration data block, or
Byte 0 = status detail code; Byte 1 = 0
