"Opengear has begun shipping a line of "smart" Linux-based
cellular routers. The ACM5004-G routers support remote management
via 3G, offering console server functionality and control of
devices with serial, USB, Ethernet and digital I/O interfaces.
"First announced in March, the ACM5004-G was touted at the time
as being the first serial device server to offer remote monitoring
over 3G cellular network devices. The ACM5004-G offers network
administrators all of the functionality of Opengear's console
servers, such as power control and distributed site management, and
makes it accessible through a 3G connection, says the company."
