A hardware 73device may be supported with a character or block 74.Em device driver , 75or it may be used within the networking subsystem and have a 76.Em network interface driver . 77Block and character devices are accessed through files in the file 78system of a special type; see 79.Xr mknod 8 . 80Network interfaces are indirectly accessed through the interprocess 81communication facilities provided by the system; see 82.Xr socket 2 . 83.Pp 84A hardware device is identified to the system at configuration time 85and the appropriate device or network interface driver is then compiled 86into the system. When the resultant system is booted, the 87autoconfiguration facilities in the system probe for the device 88and, if found, enable the software support for it. 89If a device does not respond at autoconfiguration 90time it is not accessible at any time afterwards. 91To enable a device which did not autoconfigure, 92the system will have to be rebooted. 93.Pp 94The autoconfiguration system is described in 95.Xr autoconf 4 . 96.Sh LIST OF DEVICES 97The devices listed below are supported in this incarnation of 98the system. Pseudo-devices are not listed. 99Devices are indicated by their functional interface. 100Occasionally, new devices of a similar type may be added 101simply by creating appropriate table entries in the driver; 102for example, new 103.Tn CS/80 104drives. 105.Bl -column grf/ite -offset indent 106apci APCI UART driver 107ct 7946/9144 CS/80 cartridge tape 108dca 98644 built-in serial interface 109dcl HP 98628A communications link 110dcm HP 98642A communications multiplexer 111dio DIO/DIO-II bus 112dnkbd Domain keyboard 113dvbox HP98730 ``DaVinci'' device interface 114fhpib ``fast'' HP-IB interface 115frodo Frodo ASIC (a.k.a.
