Probable inaccuracy..

5Kbytes = 40Kbits
28.8 is 28.8Kbits

Modems transmit in Bits, files are usually listed Kbytes.

True. I was just playing around with graphics and if you took a fairly
detailed GIF at 640x480x256 colors and converted it to 160x120x16 colors, it

was around 5k in size. With that, an entire frame could be sent each second
so at 28.8. An entire frame, not just a partial screen update.

So, the Nasa screens should be much faster since cuseemee does partial
updating, not an entire new frame.

But when I try to go to Nasa, I get the bottom 1/16 inch of the picture.
