par[hex]
Parameters
hex
a hexidecimal string (not case sensitive) consisting of a whole number of bytes.
Remarks
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.
Example
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.
