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
