All P configuration parameters must be ignored and kept in 0 (zero), because they are not used.

This Driver can be configured on the properties window of the I/O Driver object, inserted in an application developed using an Elipse Software product. This Driver, when added to a new application project, is loaded with the following default extra parameter configurations for the serial port:

•Baud rate of 9600 bps

•Eight data bits

•One stop bit

•No parity check

•DTR and RTS controls set to On

Possibly the serial port number can be modified to the one users want to establish communication (COM2, COM3, and so on). Also, its time-out is already defined as 1000 ms, but this is rather arbitrary and depends on the application requirements.

A modem can also be configured with another baud rate. Change this Driver's baud rate to the one configured on the modem.

Finally, check if it is necessary to enable receiving echo suppressing (Enable ECHO suppressing). Modems have this feature, which may or may not be enabled.

For other physical layers, the extra parameter configuration must be carefully observed to meet communication requirements.
