I have an IBM RS/6000 43P running AIX as its O/S and I'm not sure what kind of parallel port it is...but need it to be ECP....how can I check this?

Right off the top of my head I can think of a couple of ways:

1. Look through the specifications in the documentation that came with your server
2. Look through the documentation on your server available at the IBM website.
3. Talk to your IBM vendor or IBM Tech support.

1. Bought used - no doc.
2. did - only says it is a 25-pin parallel port
3. this computer is old and we have no tech support from IBM.

According to this PDF file from IBM's web site

At least some versions of the RS6000 43P have IEEE 1284 + ECP printer ports.

While you may get no verbal support response from IBM, they have a large number of documentson their web site for many of their systems.

I've since found, using: lsdev, that the lp0 is only a regular Parallel Port...not ECP. We're buying an ECP/EPP Parallel to get it working.

Most of these are EPP. (From my memory, not 100%)
Do you have a breakout box?
Why do you need DMA transfers?
EPP is actually more reliable, and much faster than SPP.
