Connection methods
You can connect the MP modem to a USB, Ethernet (RJ45), or serial (DB9) port
on a computer. When connected to a USB or Ethernet port, the MP modem
behaves like a network card. When connected to a serial port, the MP modem
behaves like a dial-up modem.
The MP modem also supports connections via IEEE802.11b/g if you are
implementing a WiFi version.
USB
The MP is equipped with a USB port which increases the methods by which you
can send and receive data from a connected computer. The USB port can be set
to work as either a virtual Ethernet port or a virtual serial port. A driver installation
is required to use the USB port in either mode.
Note: It is recommended that you use a USB 2.0 cable with your MP and connect directly
to your computer for best throughput.
Virtual serial port
The MP modem supports one virtual serial port over USB and one virtual serial
port over Ethernet. This VSP can be used, for example, to send AT commands, or
to run applications such as HyperTerminal
