Using the Modem in Linux or Android based Devices

Linux and Android users can use either the serial port or USB port to talk to the modem.
Continue below to learn about using the serial port, or go to
Linux or Android to learn how to install and use the USB port in Linux or Android based
systems..
Using the Serial port with Linux or Android
If you have not already plugged in a serial cable between your windows device and the
modem go ahead and do that now. If you want to use the modem's header to access the
serial port, please see Chapter
To talk to the modem you typically set your com port speed to the modem's default
speed of 115200 bps. If your application requires the modem to use a different serial
port speed, you will need to set the modem up to use this speed. Changing the serial
port speed is done using the AT+IPR command. The format of the AT+IPR command is:
Where <speed> is the desired serial port speed in bps. Available speeds are 300, 600,
1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, or 230400. More detailed
information on the AT+IPR command can be found in the Huawei AT Command manual.
This manual is available at www.zoomtel.com/4575support.
To send the command, you can use the Linux console or download an open source
terminal program. Remember that after you send that AT+IPR command to change the
serial port speed, you will need to change the serial port speed of your terminal program
to continue to talk to the modem.
