ADCCP NRM
Operations
This chapter describes some of the ADCCP NRM operations using the control packets
described in Chapter 3. Section 4.1 describes normal operational procedures.
Section 4.2 and Section 4.3 describe special conditions and performance consider-
ations.
4.1 Normal Operation of the Client/ICP Control Interface
The following discussion emphasizes the normal sequence of events and resulting con-
trol packet exchanges between the client and the ICP. The discussion identifies the
influence of ADCCP operational states upon this exchange and outlines procedures the
client must follow to achieve correct operation. These control packet exchanges may be
initiated individually by a client application using Raw
dlWrite commands, or (if the
cfglink configuration parameter is set to “yes” in the DLI configuration file) the DLI
sends and receives these packets when the client application calls
dlOpen. If the DLI
sends these packets, it constructs each packet using information extracted from the DLI
configuration file (see Chapter 5) — this is how
dlOpen configures the link/station
according to the parameters specified in the DLI configuration file.
4.1.1 Setting Maximum Data Buffer Size
The ADCCP NRM interface software assumes that the maximum data size is 512 bytes.
The client may only override this default immediately following the ICP download pro-
cedure.
