how to connect a HP-UX 11 box to a Win PC via the parallel port

Naeem_2 — Mon, 20 Oct 2003 10:06:29 GMT

Well, the question says it all. Has anyone ever tried this before and been successful?
I have carried out extensive searches and got nowhere. If it is not clear what I'm trying to do, this may help:

I have a run of the mill laptop and a HP box - I would like to connect the two using a parallel cable. Yes, I have tried an Ethernet crossover and that works, I just want to get this working too.

Any help would be greatly appreciated.

The Centronics driver will support bi-directional communication (man 7 cent for details) but there is no network-layer software to use this port. If you want to write your own communications software to do this then feel free but otherwise ....

On the other hand, serial-to-serial is a supported network topology and would require nothing special.

Like many questions, this one begs the 'what do you want to do' response.

You might get a character connection by editng /etc/inittab. and setting the device as the parrallel port so that you can run a getty. This would give you basic terminal access, ( I know this works on other platforms.)
but you can do that easy enough through windows with something like hypterm.

The commands to send are dictated by the last entry on the initab entry, and refer to a label in /etc/gettydefs. This is where parallel port specific commands could go, but I don't see any there in my version, 11.0.

Use the PPP serial LAN connection for a 9 pin RS 232 and remap into a 25 pin.

Here's a link or two on PPP and SLIP:

Oh, I almost forgot, you can get a 25 pin to 9 pin step down adaptor if need be. Any COMPUSA.

Looks like c program talking to the ports. I wonder if the HP server you are using has a bi-directional port.

It might be easer to have serial to parallel convertor connection
Serial on the HP side parallel port on the pc side:
