It was actually quite swift. Because all the web pages and data served had to fit into the code space, the html was kept small. We served graphics off a PC (except for a couple of GIFs in the 1-2k range). We also served off the 8051 a Java applet (necessary for security reasons in Java), which then made a TCP connection back to the 8051 to display the current traffic on the CAN bus it was connected to. It was able to keep up just fine with the traffic we tested it with at 125kbps.

Hi Andrew,

So how did it perform ? How much servicing time did it need to do the UDP or TCP bits ? I suppose since its only on a phone line you were only looking at stuff at up to 56K /sec ?
