# DialUp Plugin Specification

Allows serial port and IrDA modem network connections.

Adds two service types in the Network Settings - one for serial ports such as CF modem cards, the other for IrDA connections.

Status: RT

## Use Cases

- CF modem

  User inserts CF modem, selects the dialup connection, and uses the internet.

- IrDA via cellphone

  User places an IrDA phone within range, selects the dialup connection, and uses the internet.

- Demand dialing

  User inserts CF modem or places an IrDA phone within range, and use the internet. The modem is dialed automatically (user has earlier enabled that option).

- ISP configuration

  When user subscribes to an ISP, he receives a disk containing setup software, including a package for Qtopia, which includes phone number and other configuration details. User installs the package and then has dialup access without manual configuration.

## Features

- Parameterized: most parameters for the ppp connection can be set by defaults in a configuration file, so that, for example, an ISP can provide a complete service definition that the user just enables and uses - with the phone number, password, etc., predefined.
- Serial modem: when a CF modem is inserted, the dialup services become available (see Network Monitor applet).
- IrDA modem: available when the user has enabled IR (not implemented: and a phone is discovered).

## Prerequisites

- IrDA discovery: the irda service (/etc/rc.d/init.d/irda) must run irattach in discovery mode (-s option).
