1 or 2
Stop Bits
Stop bits signal the end of a character in the data stream. For most applications,
use one stop bit. For slower devices that require more time to re-synchronize,
use two stop bits.
All devices communicating through this port must use the same number of stop
bits.
0 to 65535 milliseconds
RTS On
This parameter sets the number of milliseconds to delay after Ready To Send
(RTS) is asserted before data will be transmitted.
0 to 65535 milliseconds
RTS Off
This parameter sets the number of milliseconds to delay after the last byte of
data is sent before the RTS modem signal will be set low.
Y ES or N O
Use CTS Line
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.
0 to 10
Retry Count
This parameter specifies the number of times a command will be retried if it fails.
0 to 10000 milliseconds
Request Timeout
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.
0 to 10000 milliseconds
Busy Timeout
This parameter specifies the number of milliseconds to wait for the pass-through
port to become available.
