6.3Serial Connection Setup

Setting the Baud Rate

1.Select Serial ä Baud Rate.

2.Select a baud rate for the connection between the modem and I/O device.

The options range from 1200 to 38400.

Setting the Data Bits

1.Select Serial Data Bits.

2.Select the number of data bits per byte sent from the I/O device. The

options are 7 or 8 bits per byte.

Setting the Stop Bits

1.Select Serial ä Stop Bits.

2.Select the number of number of bits used to designate the end of a

byte. The options are 1 or 2 bits.

Setting the Transmit Character Timeout

1.Select Serial ä Transmit Character Timeout.

2.Enter the expected pause between data strings through the serial port.

The value must be in the range 10 9999 milliseconds.

Setting the Flow Control Option

1.Select Serial ä Flow Control.

2.Select from the following options:

1-NoneDo not use flow control.

2-RTS/CTSMonitor the Ready To Send (RTS) signal to determine when to send data to the serial device and assert CTS to tell the serial device when it can send data to the modem.

3-XON/XOFFUse special ASCII characters to determine when to

send/receive data to/from the serial device.

Setting the DCD Mode

1.Select Serial ä DCD Mode.

2.Select from the following options:

1-EnableIn this mode the modem asserts the DCD line when it is receiving data over-the-air.

2-DisableIn this mode the modem asserts the line when it is in a normal operating state and negates the line when it is in a programming state.
