REFERENCES

If the modem does not receive an ACK, DATA or NACK, transmission is ended after

the RX Timeout (see par. 2.2.3 ). See also Radio Protocol Timeout, par. 2.5.3, for

radio transmission to RF devices.

For ACK/NACK selection when STARModem™ as Client, is transmitting to a

destination device connected to a Remote Host refer to par. 2.1.

2.2.3 RX Timeout

This parameter can be used to automatically end data reception from the Local Host

after the specified period of time.

If no character is received from the Local Host, after the timeout expires, any

incomplete string is flushed from the modem buffer.

Refer to par. 2.2.5 for RX Timeout functioning wh

en defining the frame packing.

2.2.4 FIFO

If enabled, the Destination Device collects all messages sent by STARModem™

and sends them in the order of acquisition to the connected Remote Host.

If disabled, STARModem™ blocks the message transmission from the Local Host

until an answer signaling the right/wrong message transmission has been received

from the RF Destination Device (1 way) or the Remote Host (2 way). Once the

answer has been received, the Local Host is allowed to send a new message.

This command requires the Modem (RTS/CTS) handshaking to be enabled.

For more details about the Transmission Mode refer to par. 2.5.2.
