WRITING APPLICATIONS THAT USE 6100 MPS-B

Disconnect Modem

This form of the CONTROL request is used to explicitly disconnect

the line. It drops Data Terminal Ready (DTR) and waits for Data

Set Ready (DSR) to drop. The wait interval for DSR to drop is

determined by the connect timeout line configuration parameter

MPSBCONNWCTTIMEOUT (the value of MPSBCONNECTTIMEOUT must be

greater than zero).

The request buffer format is:

Function := 67

Modifier := 18

Request ID := A unique value from 1 to 32767,

application-dependent

Text Out := Doesn’t matter

Text In := Doesn’t matter

Text := Null

The response buffer format is:

Function := 67

Status := 0 if the operation completed successfully, or

140 if DSR did not drop within time interval

Request ID := The same as in the request

Text Out := 0

Text In := 0, or

2 if status detail code is present in Text field

Text := Null, or

Byte 0 = status detail code; Byte 1 = 0
