Waiting for an Incoming Call
Your application waits for an Incoming Call that has been directed by PTP to the
subdevice that it has opened.
•
CONTROL 11 (data-exchange modes 0, 1, 2, and 3):
If the CONTROL operation completes normally, the circuit is established and an
Incoming Call has been received.
•
READ (data-exchange mode 2):
If the READ procedure completes normally and an Incoming Call (buffer format) is
in the read buffer, then your application program must WRITE a Call Accepted
(buffer format) or WRITEREAD a Clear Request (buffer format).
No other Call Requests are routed to the subdevice until the call is cleared.
Posting a Call Request
•
CONTROL 17 (data-exchange modes 0, 1, 2, and 3):
A Call Request is sent and a network response received. If the CONTROL
operation completes normally, the call has been accepted.
