Most dialup modems are not supported by Ubuntu, but drivers can be found that will enable the use of some such modems. First you need to identify what chipset your dialup modem is:
-
Download scanmodem (http://linmodems.technion.ac.il/packages/scanModem.gz) using a computer with an Internet connection.
-
Copy the downloaded file to the Home folder of the computer with the dialup modem you wish to use.
-
Open a Terminal (Enter after each line:
→ → ) and type the following commands, pressinggunzip -c scanModem.gz > scanModem chmod +x scanModem sudo ./scanModem gedit Modem/ModemData.txt
-
A file containing information on the chipsets used by any detected modems should open. Print or save the information.
