par[hex]
Parameters
hex
a hexidecimal string consisting of a whole number of bytes.
Remarks
These bytes are input samples from the parallel port bits which have been selected as inputs using the pardir and parhs commands. These samples could have been initiated from either a parread command or harware input handshaking.
Example
lowlevel:par[5A] indicates that the bits 01011010 are present on the port (assuming all bits are set to input).
