A shell script to set up a PPP connection with a remote Bluetooth device.

Modememu is a simple tool which can be used to emulate a modem to a remote Bluetooth device. It can be used to connect from a remote Bluetooth stack that supports only the dialup networking profile. The Compaq iPaq with the Socket Bluetooth card is an example where this program is useful. It can also be used to connect from a windows machine using direct cable connection over Bluetooth. The sample services file in /etc/affix gives an example how to use it.
