DATA COMMUNICATION OPERATION

The Fax/Data Modem may be used to connect to an On-Line service, local BBS (Bulletin Board System) or the Internet. This connection may require different communication parameters. The following parameters are the basic settings needed for a successful connection:

1.	Data Bit	8	Data bit is the most common setting.
		7	Data bit some for On-Line service and mostly Main frame connection.
2. Stop Bit		1	Stop bit is widely use.
3.	Parity	There are three setting: ODD, EVEN or NONE depends on the system you are trying to connect.
4.	Baud Rate	The speed that the data traveling between the modem and your computer. The setting should be four times of your modem speed. For example:

Modem Speed

Baud Rate selection

2400 bps

9600 bps

9600 bps

38,400 bps

14,400 bps

57,600 bps

28,800 bps

115,200 bps

5. Flow Control	Set the flow control between the computer and the modem can prevent data over run during transmission. There are two common ways of setting the flow control.
	Software Flow control or XON/XOFF
	Hardware Flow Control or CTS/RTS

Most of the data communication software has the option for setting the above parameters. In order to let the modem communicate flawlessly, these settings must be identical between the two modems except Baud Rate and Flow Control.
