Serial Connector (9 way D)
Output via serial
The following program will output serial data at 2400 baud which reports the incrementing value of the byte variable 'b0' every second. As the serial signal goes directly to a 9-way D the polarity of the serial is 'normal' so an 'n2400' baud rate is used. Because an 8-bit byte variable is used, after the number reaches 255, the next increment will take its value to zero.
- Code Example:
main: serout B.1, n2400, ( #b0, CR, LF ) ; Output a number value
pause 1000 ; Wait for 1 second
b0 = b0 + 1 ; Next number to output
goto main ; Output the next number
