How can PC printer port bits be driven directly from pd? I'd like to write to I/O port 378 with byte values from 0 to 255 to control 8 port bits at a time. I can run pd under Win98, Win2000, WinNT, or Linux. I suspect this may be easiest under Win98 (no I/O protection). Any suggestions would be welcome.
Thanks. Lex

With a new external I'm now programming! It should be ready later this week, I'll let you know...

How does your object differ from [lp] in zexy?

It controls each pin independantly.

Could this be integrated with the already existing external ? I think it would be cool to have one externals that fully supports the parallel port.

I don't think so; my external is simply a flext wrapper for the parapin library: http://www.circlemud.org/~jelson/software/parapin/

This lib seems similar to the user-space parallel port driver that's in the linux kernel (ppdev). Does it have any relation? If this kernel module provides the same access, it might be the better option since its included with linux. But I'm not trying to throw a wrench in your plans :)

Using the parapin library is probably easier to use than fiddling with the ppdev driver. The library size is only 3K and the external is almost ready. So don't wrench in my plans! ;-)

btw. can't you control each pin independantly with [lp] ? as you have to set all the pins at once, you will just have to write an abstractions, that ANDs the separate bits.
at least, that's how i do it

My parapin external also read the pins; pins 10, 11, 12, 13 and 15 are permanent inputs, pins 1, 2-9, 14 16 and 17 are either inputs or outputs. Pins 2-9 are the "data" pins, and are either all inputs or all outputs. I hope to release a first version of the external tonight...
