For whatever its worth, because I know there's a few other threads mentioning this unit but not much answers...
I have a Data IO 29A with Unipak. I messed with it for some time last night on an XP machine with the various versions of Promlink with no luck - while the unit itself can send serial info (characters) to a terminal program fine, and it seems it can read what the computer is sending it, it still errored out with "Command Error 17" on any action.
Today I took an old USB key and made it dos bootable with Windows 98. Copied all the available versions of Promlink over to it as well and went to town. Long story short, both 3.4 (set to 29B with Unipack) and the older 2.6 version (proper) worked great on DOS. If you have a computer that boots from a floppy, you should have no problem fitting the older versions of Promlink onto a dos bootable 1.4meg floppy.
In addition, the 2.6 version had all the various Signetics proms listed, as well as 2708's for AMD and Intel, whereas the 3.4 had a problem with the device file and did NOT list 2708 support (not often needed but when working with b/w's a lot I wish I could at least test them - now I can!)
Promlink 6.1 did NOT work with the 29A - I wouldn't even try. the oldest version seemed to have the best results and worked fine.
You can find Promlink here: http://home.myfairpoint.net/mlps_vt/promlink.htm
As for cabling, I used a regular modem cable (9 pin female to 25 pin male), as well as a null modem adapter.
Hope this helps someone!
