Overview
Modem is a network device that is widely used. It is important for a router to properly manage and
control the use of modem in a network. However, there are many modem manufacturers and various
modem models. Even though all of them support the AT command set and are compliant with the
industry standard, each type of modem differs somewhat on the implementations and command details.
The router provides the following functions for managing a modem:
1) Intercommunicating with the equipment from other vendors. The asynchronous serial interfaces of
the participating parties are working in flow mode interconnected via modems.
2) Providing rich debugging information for modem maintenance and monitoring.
