2.6.11 Use CTS Line
YES or NO
This parameter specifies if the Clear To Send (CTS) modem control line is to be
used or not. If the parameter is set to NO, the CTS line will not be monitored. If
the parameter is set to YES, 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.
