It was perfect for using Trax's MFC phreaking methods.
Mendax also used the system for scanning. Most of the time, he picked telephone prefixes in the Melbourne CBD. When his modem hit another, Mendax would rush to his computer and note the telephone number for future hacking exploration.

It was strange behaviour for someone who had spent most of his teenage years trying to connect to the outside world through telephone lines and computers, but Mendax had
