Devices and X.25 Virtual Circuits

A number of devices are used for X.25 within the system. They are either used for system management or they are mapped to an individual virtual circuit.

Management Devices

X.25 Incoming Call Handling

The device /dev/x25spi allows an application program to scrutinize every Incoming Call packet that arrives before it becomes visible to other programs or processes.

The x25daemon uses this device to collect incoming calls from the network and process them according to the information in x25incalls. It records its activities in /usr/spool/x25/x25dlog.

Devices for tty Access on UnixWare

UnixWare systems use a streams interface for tty support rather than the traditional character interface. For this reason, tty access on UnixWare systems uses the device /dev/xptty. This device is provided by a cloning streams driver (xpt), which the install script will add to your system. The xpt driver currently does not support dial strings, so it cannot be used for outgoing tty calls.

Device names for getty/login

The xpt devices (/dev/xptty) are used with getty and login on UnixWare systems.
