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.

YES or NO

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.
