Install
Install the driver and create a node in the /dev directory by:
#insmod plcm_drv.ko
#mknod /dev/plcm_drv c 248 0
Note:
If you cannot install the driver, check whether you have enabled the parallel port in the BIOS setting .
Once the message of “insmod”: error inserting ‘plcm_drv.ko’: -1 Input/output error” appears, please
check that whether the major number is repeated or not. The major number needed with the “mknod”
command varies with different software versions; please look up the Readme file for this value.
