A hardware 66device may be supported with a character or block 67.Em device driver , 68or it may be used within the networking subsystem and have a 69.Em network interface driver . 70Block and character devices are accessed through files in the file 71system of a special type; see 72.Xr physio 4 73and 74.Xr mknod 8 . 75Network interfaces are indirectly accessed through the interprocess 76communication facilities provided by the system; see 77.Xr socket 2 . 78.Pp 79A hardware device is identified to the system at configuration time 80and the appropriate device or network interface driver is then compiled 81into the system. When the resultant system is booted, the 82autoconfiguration facilities in the system probe for the device 83on either the 84.Tn UNIBUS 85(or 86.Tn Q-bus ) 87or 88.Tn MASSBUS 89and, if found, enable the software 90support for it. If a 91.Tn UNIBUS 92device does not respond at autoconfiguration 93time it is not accessible at any time afterwards. To 94enable a 95.Tn UNIBUS 96device which did not autoconfigure, the system will have to 97be rebooted. If a 98.Tn MASSBUS 99device comes 100.Dq on-line 101after the autoconfiguration sequence 102it will be dynamically autoconfigured into the running system. 103.Pp 104The autoconfiguration system is described in 105.Xr autoconf 4 . 106A list of the supported devices is given below. 107.Sh SEE ALSO 108.Xr intro 4 , 109.Xr netintro 4 , 110.Xr autoconf 4 , 111.Xr config 8 . 112.Rs 113.%T "Building 4.3 BSD UNIX Systems with Config" 114.%B SMM 115.%N 2 116.Re 117.Sh LIST OF DEVICES 118The devices listed below are supported in this incarnation of 119the system. Pseudo-devices are not listed. 120Devices are indicated by their functional interface. 121If second vendor products provide functionally identical interfaces 122they should be usable with the supplied software. 123.Bf -symbolic 124Beware, 125however, that we promise the software works 126ONLY with the hardware indicated on the appropriate manual page. 127.Ef 128Occasionally, new devices of a similar type may be added 129simply by creating appropriate table entries in the driver. 130.Pp 131.Bl -column tmscp -offset indent 132acc ACC LH/DH IMP communications interface 133ad Data translation A/D interface 134css DEC IMP-11A communications interface 135crl VAX 8600, 8650 console RL02 disk 136ct C/A/T or APS phototypesetter 137ddn ACC ACP625 DDN Standard Mode X.25 IMP interface 138de DEC DEUNA 10Mb/s Ethernet controller 139dh DH-11 emulators, terminal multiplexor 140dhu DHU-11 terminal multiplexor 141dmc DEC DMC-11/DMR-11 point-to-point communications device 142dmf DEC DMF-32 terminal multiplexor and parallel printer interface 143dmz DEC DMZ-32 terminal multiplexor 144dn DEC DN-11 autodialer interface 145dz DZ-11 terminal multiplexor 146ec 3Com 10Mb/s Ethernet controller 147en Xerox 3Mb/s Ethernet controller (obsolete) 148ex Excelan 10Mb/s Ethernet controller 149fl VAX-11/780 console floppy interface 150hdh ACC IF-11/HDH IMP interface 151hk RK6-11/RK06 and RK07 moving head disk 152hp MASSBUS disk interface (with RP06, RM03, RM05, etc.) 153ht TM03 MASSBUS tape drive interface (with TE-16, TU-45, TU-77) 154hy DR-11B or GI-13 interface to an NSC Hyperchannel 155ik Ikonas frame buffer graphics device interface 156il Interlan 1010, 1010A 10Mb/s Ethernet controller 157ix Interlan NP-100 10Mb/s Ethernet controller 158kg KL-11/DL-11W line clock 159lp LP-11 parallel line printer interface 160mt TM78 MASSBUS tape drive interface 161np Interlan NP-100 10Mb/s Ethernet controller (intelligent mode) 162pcl DEC PCL-11 communications interface 163ps Evans and Sutherland Picture System 2 graphics interface 164qe DEC DEQNA Q-bus 10 Mb/s Ethernet interface 165rx DEC RX02 floppy interface 166tm TM-11/TE-10 tape drive interface 167tmscp TMSCP-compatible tape controllers (e.g., TU81, TK50) 168ts TS-11 tape drive interface 169tu VAX-11/730 TU58 console cassette interface 170uda DEC UDA-50 disk controller 171un DR-11W interface to Ungermann-Bass 172up Emulex SC-21V, SC-31 UNIBUS disk controller 173ut UNIBUS TU-45 tape drive interface 174uu TU58 dual cassette drive interface (DL11) 175va Benson-Varian printer/plotter interface 176vp Versatec printer/plotter interface 177vv Proteon proNET 10Mb/s and 80Mb/s ring network interface 178.El 179.Sh HISTORY 180The section 4 181.Nm intro 182appeared in 183.Bx 4.1 . 184
