The whole point of writing this script was to try and convince other non-CI's, i.e. hobbyists, that it really pays to learn prontoscript and how to deal with http servers. All of the manufacturers I have spoken to over this past year indicate they will be dropping RS232 in favor of IP.

As that happens direct control of A/V devices from the pronto will be the way to go. No extenders in the loop.

It is not that hard. As Lyndel said go slow and read the book, read samples and it will become obvious. If you have never done real programming (coding in a language like C or VB or Java or. . . you have a slight advantage. You won't keep getting the nuances of syntax confused all the time as you will only know one, javascript.
