I have a customer that has an older ADIX that they need some minor programming changes made to that I am having difficulty connecting to. I connect to the PC port on their EDVIF card (the CPU card is old enough that it does not have a PC programming connector), but can never get further than 80% when attempting to connect to it. I'm using the same hardware that I always use to connect to ADIX systems (Keyspan USA-19HS and FAX-065 adapter), and have tried every combination of port speeds and settings that I can think of but still can not connect to it.

Any ideas on what I might be able to do to get this connected, or am I resigned to having to dig out the manual and program the key patterns through the attendant phone?

What's the software version you're trying t connect to? If your processor lacks an 8 pin connector, you're working with a CPU16M maybe? If it's THAT old, you need a DOS programmer that matches the installed software version. A Windows based programmer won't reliably work for any software version before 6.0 .

Some of the earlier ECS Utilities discs had copies of the older programmers in the archive folder. If you have one of those, try one of them.
