A hardware 69device may be supported with a character or block 70.Em device driver , 71or it may be used within the networking subsystem and have a 72.Em network interface driver . 73Block and character devices are accessed through files in the file 74system of a special type; see 75.Xr mknod 8 . 76Network interfaces are indirectly accessed through the interprocess 77communication facilities provided by the system; see 78.Xr socket 2 . 79.Pp 80A hardware device is identified to the system at configuration time 81and the appropriate device or network interface driver is then compiled 82into the system. When the resultant system is booted, the 83autoconfiguration facilities in the system probe for the device 84and, if found, enable the software support for it. 85If a device does not respond at autoconfiguration 86time it is not accessible at any time afterwards. 87To enable a device which did not autoconfigure, 88the system will have to be rebooted. 89.Pp 90The autoconfiguration system is described in 91.Xr hp300/autoconf 4 . 92.Sh LIST OF DEVICES 93The devices listed below are supported in this incarnation of 94the system. Pseudo-devices are not listed. 95Devices are indicated by their functional interface. 96Occasionally, new devices of a similar type may be added 97simply by creating appropriate table entries in the driver; 98for example, new 99.Tn CS/80 100drives. 101.Bl -column grf/ite description -offset indent 102.It com serial interfaces (98644, 98626, and built-in apci and dca) 103.It ct 7946/9144 CS/80 cartridge tape 104.It dcm HP 98642A communications multiplexer 105.It dio DIO/DIO-II bus 106.It dnkbd Domain keyboard 107.It dvbox HP98730 ``DaVinci'' device interface 108.It fhpib ``fast'' HP-IB interface 109.It frodo Frodo ASIC (a.k.a.
