A hardware 39device may be supported with a character or block 40.Em device driver , 41or it may be used within the networking subsystem and have a 42.Em network interface driver . 43Block and character devices are accessed through files in the file 44system of a special type; see 45.Xr physio 4 46and 47.Xr mknod 8 . 48Network interfaces are indirectly accessed through the interprocess 49communication facilities provided by the system; see 50.Xr socket 2 . 51.Pp 52A hardware device is identified to the system at configuration time 53and the appropriate device or network interface driver is then compiled 54into the system. When the resultant system is booted, the 55autoconfiguration facilities in the system probe for the device 56on either the 57.Tn UNIBUS 58(or 59.Tn Q-bus ) 60or 61.Tn MASSBUS 62and, if found, enable the software 63support for it. If a 64.Tn UNIBUS 65device does not respond at autoconfiguration 66time it is not accessible at any time afterwards. To 67enable a 68.Tn UNIBUS 69device which did not autoconfigure, the system will have to 70be rebooted. If a 71.Tn MASSBUS 72device comes 73.Dq on-line 74after the autoconfiguration sequence 75it will be dynamically autoconfigured into the running system. 76.Pp 77The autoconfiguration system is described in 78.Xr autoconf 4 . 79A list of the supported devices is given below. 80.Sh SEE ALSO 81.Xr intro 4 , 82.Xr netintro 4 , 83.Xr autoconf 4 , 84.Xr config 8 . 85.Rs 86.%T "Building 4.3 BSD UNIX Systems with Config" 87.%B SMM 88.%N 2 89.Re 90.Sh LIST OF DEVICES 91The devices listed below are supported in this incarnation of 92the system. Pseudo-devices are not listed. 93Devices are indicated by their functional interface. 94If second vendor products provide functionally identical interfaces 95they should be usable with the supplied software. 96.Bf -symbolic 97Beware, 98however, that we promise the software works 99ONLY with the hardware indicated on the appropriate manual page. 100.Ef 101Occasionally, new devices of a similar type may be added 102simply by creating appropriate table entries in the driver. 103.Pp 104.Bl -column tmscp -offset indent 105acc ACC LH/DH IMP communications interface 106ad Data translation A/D interface 107css DEC IMP-11A communications interface 108crl VAX 8600, 8650 console RL02 disk 109ct C/A/T or APS phototypesetter 110ddn ACC ACP625 DDN Standard Mode X.25 IMP interface 111de DEC DEUNA 10Mb/s Ethernet controller 112dh DH-11 emulators, terminal multiplexor 113dhu DHU-11 terminal multiplexor 114dmc DEC DMC-11/DMR-11 point-to-point communications device 115dmf DEC DMF-32 terminal multiplexor and parallel printer interface 116dmz DEC DMZ-32 terminal multiplexor 117dn DEC DN-11 autodialer interface 118dz DZ-11 terminal multiplexor 119ec 3Com 10Mb/s Ethernet controller 120en Xerox 3Mb/s Ethernet controller (obsolete) 121ex Excelan 10Mb/s Ethernet controller 122fl VAX-11/780 console floppy interface 123hdh ACC IF-11/HDH IMP interface 124hk RK6-11/RK06 and RK07 moving head disk 125hp MASSBUS disk interface (with RP06, RM03, RM05, etc.) 126ht TM03 MASSBUS tape drive interface (with TE-16, TU-45, TU-77) 127hy DR-11B or GI-13 interface to an NSC Hyperchannel 128ik Ikonas frame buffer graphics device interface 129il Interlan 1010, 1010A 10Mb/s Ethernet controller 130ix Interlan NP-100 10Mb/s Ethernet controller 131kg KL-11/DL-11W line clock 132lp LP-11 parallel line printer interface 133mt TM78 MASSBUS tape drive interface 134np Interlan NP-100 10Mb/s Ethernet controller (intelligent mode) 135pcl DEC PCL-11 communications interface 136ps Evans and Sutherland Picture System 2 graphics interface 137qe DEC DEQNA Q-bus 10 Mb/s Ethernet interface 138rx DEC RX02 floppy interface 139tm TM-11/TE-10 tape drive interface 140tmscp TMSCP-compatible tape controllers (e.g., TU81, TK50) 141ts TS-11 tape drive interface 142tu VAX-11/730 TU58 console cassette interface 143uda DEC UDA-50 disk controller 144un DR-11W interface to Ungermann-Bass 145up Emulex SC-21V, SC-31 UNIBUS disk controller 146ut UNIBUS TU-45 tape drive interface 147uu TU58 dual cassette drive interface (DL11) 148va Benson-Varian printer/plotter interface 149vp Versatec printer/plotter interface 150vv Proteon proNET 10Mb/s and 80Mb/s ring network interface 151.El 152.Sh HISTORY 153The section 4 154.Nm intro 155appeared in 156.Bx 4.1 . 157
