Intel AMT serial-over-lan client.
AMT (included in Intel vPro and Centrino Pro) provides out-of-band (OOB) management for Desktops and Laptops, using an agent integrated in the network adapter and in the motherboard.
Serial-over-lan provides a secure way to connect a remote computer, through a pseudo serial interface.
amtterm and gamt are two terminal tools to connect to that pseudo serial interface from a remote computer. amttool is a perl script to gather information about and remotely control AMT managed computers.
