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:
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.
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
