4.1 RADIO AND SERIAL COMMUNICATION CONTROLS


DLCC communication can be controlled by several parameters depending on
whether it is a Client or Server. DLCC can act as both Client and Server.

The following table summarizes which parameters are controlled by the Client and
which ones are controlled by the Server.

Client (Transmitter)

controlled parameters:

Server (Receiver)

controlled parameters

Transmission Mode

ACK/NACK Protocol

ACK/NACK From Remote Host

Handshaking

FIFO
Handshaking
Single Store


NOTE

To avoid incorrect interpretation of ACK characters, ACK/NACK
Protocol and ACK/NACK From Remote Host cannot be
simultaneously enabled on the same DLCC.



To help understand the various communication control possibilities among the
different communication modes, we will analyze the communication control
parameter settings for the following 3 cases:

1) DLCC acting as Server

2) DLCC acting as Client (like an RF device)

3) DLCC as client / server
