SERIAL PORTs 9, 10, and 11 SERIAL PORTs 9, 10, and 11

SERIAL PORTs 9, 10, and 11

The serial ports are used to input and output serial data for entering

programs, printing tests results and screen images, and sending test

results to a connected controller, disk drive, or terminal.

Operating Considerations

The serial communications settings are defined on the I/O

CONFIGURE screen.

SERIAL PORT 9 must be used for serial printing.

The IBASIC controller sends and receives data to the serial ports using

address 9 for the primary port, and 10, 11 for the other ports. For

example, to enter data from the primary serial port into a program

variable named SDATA, you could use the following command:

ENTER SERIAL_9;SDATA

To send data from your program out of the primary serial port, you

could use the following command:

OUTPUT SERIAL_9;SDATA
