If DLCC 1 -
Transmission Mode = 2 ways
ACK/NACK from Remote Host = enabled
FIFO = enabled
Handshaking = any
Single Store = enabled
The Client, (Host 1) sends a message to the Remote Host (Host 2) and expects
an answer from Host 2. Host 2 answers with DATA (a string of up to 238
characters). If DLCC 2 sends this DATA answer within the Radio Protocol
Timeout, DLCC 1 sends it to its local Host (Host 1), otherwise DLCC 1 sends
NACK. In addition, the Single Store parameter upon Radio Protocol timeout,
causes DLCC 1 to retry transmission of the same message the defined number
of times, before responding to its local Host (Host 1) with NACK.
Host 1 -
Handshaking = RTS/CTS

If DLCC 1 -
Transmission Mode = any
ACK/NACK from Remote Host = enabled
FIFO = disabled
Handshaking = modem (RTS/CTS)
The Client, (Host 1) sends a message to the Remote Host (Host 2). DLCC 1
after receiving the message, blocks transmission of Host 1 until communication
is completed according to the other communication control parameter settings as
described above.
NOTE
The most secure settings for bi-directional communication is to have
ACK/NACK from Remote Host enabled and Two-way transmission at
both ends. In addition, in case the first transmission fails, the Single
Store parameter automatically repeats transmission of the same data
packet up to the number of specified attempts.
