Remove unused and unsupported code. Consult the file `DEVELOPMENT' for details. Partly based on suggestions by Gianluca Guida <glguida@gmail.com>. * i386/bogus/par.h: Remove file. * i386/i386at/if_par.c: Likewise. * i386/i386at/if_par.h: Likewise. * i386/i386at/conf.c: Don't include <par.h> anymore and adopt all users of NPAR as if it were always defined to `0'. * i386/i386at/lpr.c: Likewise.

- Subject: parallel network interface
-
- The printer network driver has the following hardware requirements for the
- interconnection cable:
-
- Connections:
- Side1 Side2 Function Side1 / Side2
- Pin 5 Pin 10 Interrupt strobe: send status (w)/send status (r)
- Pin 2 Pin 15 Data bits : write / read
- Pin 3 Pin 13 Data bits : write / read
- Pin 4 Pin 12 Data bits : write / read
- Pin 6 Pin 11 Data bits : write / read
- Pin 10 Pin 5
- Pin 11 Pin 6
- Pin 12 Pin 4
- Pin 13 Pin 3
- Pin 15 Pin 2
- Pins 18-25 Pins 18-25 (ground interconnections)
-
- The cable is "symmetric" in that either side can be plugged into either of the
- computers.
-
- The hardware requirements are as follows:
- Port 0x378 must be writable with the following specifications:
- Bit 4 -> pin 6
- Bit 3 -> pin 5
- Bit 2 -> pin 4
- Bit 1 -> pin 3
- Bit 0 -> pin 2
- Port 0x379 must be readable with the following specifications:
- Bit 7 <- pin 11
- Bit 6 <- pin 10
- Bit 5 <- pin 12
- Bit 4 <- pin 13
- Bit 3 <- pin 15
- Port 0x37a must be readable and writable with the following specifications:
- Bit 4 -> interrupt enable
- So Port 0x378 connects to Port 0x379 as
- Bit 3 -> pin 5 : pin 10 -> Bit 6 0x08 -> 0x40
-
- Bit 4 -> pin 6 : pin 11 -> Bit 7 0x08<<1 -> ~ 0x80
- Bit 2 -> pin 4 : pin 12 -> Bit 5 0x07 -> 0x38
- Bit 1 -> pin 3 : pin 13 -> Bit 4 0x07 -> 0x38
- Bit 0 -> pin 2 : pin 15 -> Bit 3 0x07 -> 0x38
- [note: bit 0 is considered the least significant bit, pins on the connector
- are numbered starting with 1, -> represents sending data out on the bus, <-
- represents reading data from the bus]
-
- Pins 1,7,8,9, and 16 are currently unused, and may be allowed to "float".
-
- The data is sent in 4 bit "nybbles", with the highest 4 bits being sent first.
-
- To bring up the interface, all that should be required is
- ifconfig par0 <your ip address> <connected machine's ip address> up
- and to bring down the interface
- ifconfig par0 down
- You may get a warning message (such as printer out of paper) once you down
- the interface, as the port is monitored for both printer and network activity
- depending on whether par0 is up or down, and when you down the interface the
- printer driver will then read whatever is on the port (which will be the last
- message from the other computer).
