Basic CS:S Rcon class by Freman. (V1.00)
----------------------------------------------
Ok, it's a completely working class now with with multi-packet responses
Contact: printf("%s%s%s%s%s%s%s%s%s%d%s%s%s","rc","on",chr(46),"cl","ass",chr(64),"pri","ya",chr(46),2,"y",chr(46),"net")
Behaviour I've noticed:
rcon is not returning the packet id.
