Well, I heard from Yale. They do not have a system up and running, despite what Unisys thinks. Oh well.
We are working hard here a Arizona on a script that goes out and gets files about once an hour. It is going to be a week or so to get it working.
They SHOULD be GIF instead of PCX. I experimented with some of Unisys' images and determined that the average image is less than half the size of the PCX file after I convert it to GIF. Considering that bandwidth is one of the major bottlenecks in the Unisys operation, they could effectively DOUBLE their bandwidth just by changing to GIF images.
Another alternative is to use 'compress' on the images. PCX images compress down to less than 1/2 of their original size. Unisys then doesn't have to worry about doing a pcx to gif so this may be simpler for them. Another option in this regard is to use IDD to distribute the data to Unisys DIFAX subscribers. I don't want to think about the bureaucratic mess one would have to go thru to get this set up. Mike
