2.6.11 Use CTS Line
Y ES
or N
O
This parameter specifies if the Clear To Send (CTS) modem control line is to be
used or not. If the parameter is set to N
O
, the CTS line will not be monitored. If
the parameter is set to Y
ES
, the CTS line will be monitored and must be high
before the module will send data. Normally, this parameter is required when half-
duplex modems are used for communication (2-wire). This procedure is
commonly referred to as hardware handshaking.
2.6.12 Retry Count
0 to 10
This parameter specifies the number of times a command will be retried if it fails.
2.6.13 Request Timeout
0 to 10000 milliseconds
This parameter specifies the number of milliseconds to wait for a complete
request message. The timer is started after the DLE-STX character sequence is
received for the full-duplex protocol or the DLE-SOH sequence for the half-
duplex protocol. If the timer expires, the current request message will be aborted.
2.6.14 Busy Timeout
0 to 10000 milliseconds
This parameter specifies the number of milliseconds to wait for the pass-through
port to become available.
2.6.15 ACK Timeout
0 to 10000 milliseconds
This parameter specifies the number of milliseconds to wait for a DLE-ACK
character sequence after a response is issued.
