Sending data out the parallel port




a hexidecimal  string (not case sensitive) consisting of a whole number of bytes.


These bytes are output to the parallel port to those bits which have been selected for output using the pardir and  parhs commands. If more than one byte is sent, the data rate is set by the IR sampling period. The last byte of data will remain present on the port indefinitely.


lowlevel:par[B35A] places the bits 10110011 on the parallel port pins (assuming all pins were selected for output) followed by 01011010 one IR sample period later. The 01011010 remains on the port.
