Paralell port not recognized in Sco Unix 5.0.7

Sco Openserver 5.0.7 was installed on a Proliant ML350 G3. The port is not recognized on boot up
I assume it is /dev/lp3. I tried to send 'date >
/dev/lp3' but the process froze. HP Smart Start diagnostics recognizes the parallel port. I also tried lp and lp0, but no luck. What next?

Set RBSU to LPT1, IRQ 7.

Run 'mkdev parallel' and configure ISA parallel port for 378-37F, IRQ 7 (/dev/lp0).

Rebuild kernel.

Run printer manager and add a local printer. Give the printer a name and device type then link to LPT0.

Test with 'lp -d nameofprinter path_of_file_to_print.

Thanks, but isn't the embedded paralled port an PCI port? mkdev parallel tels me that I am configured for pci.....the are no ISA slots on the motherboard.

No. There are no such pci parallel ports. The parallel port is an ISA device and it is part of the SuperI/O chip included in the ServerWorks chipset.

Thank you
I got lp0 recognized and working.
After installing an additional parallel port (pci), the system recognized it as lp3 as it should. However, after sending 'date > /dev/lp3' i got nonsense letters. I reset the printer and the redirected command froze without any printing. I had to kill the process with the -9 flag. The board is a 32 bit pci single parallel made by Siig. I installed it in the 32 bit slot. I will try another board
