Writing to the Parallel Port

To write the value 52 decimal (34 hex, 0011 0100 binary) to the parallel
port's output pins, use one of the following commands:
OUTPUT @Rfna;"DIAG:PORT:WRITE 15,3,52"
WRITEIO 15,3;52
When the write command is executed, the parallel port's data lines (pins
2-9) will be set to the specified value, and then a pulse of at least 1 µs
duration will occur on the strobe line (pin 1). A data setup and data hold
time of at least 1 µs are guaranteed. See
Figure 6-1.
