[fpc-pascal] Ethernet Relays

[Ched]

Hello James,

You'll find a source of happiness with unit fphttpclient .
Particularily with the simplget function:

TFPHTTPCLIENT.SIMPLEGET('http://192.168.1.4/30000/00')

It is said that it works with https also, but under the Mageia7 distro, you probably encounter problems I 
haven't yet solved. But for http, that should be right.

Cheers, Ched

Of course I can get it to work just typing the commands from a browser but that's not what I want, I want my FPC console program to send the appropriate commands whenever I want one of the relays to come on or go off.
