NAME
cpi -- parallel printer driver for Creative Systems Inc. Hurdler CPI Nubus card
SYNOPSIS
cpi* at nubus?
DESCRIPTION
The cpi interface provides access to parallel printer ports.
HARDWARE
The cpi interface supports the Creative Systems Inc. Hurdler CPI Nubus card, which is based on a Zilog Z8536 CIO. The parallel port on the Hurdler CPI card is wired as follows: Signal SubD pin Z8536 pin Z8536 signal /STROBE Strobe 1 22 PC3 D0 2 33 PA0 D1 3 32 PA1 D2 4 31 PA2 D3 5 30 PA3 D4 6 29 PA4 D5 7 28 PA5 D6 8 27 PA6 D7 9 26 PA7 /ACK 10 21 + 11 PC2 + PB3 BUSY 11 19 + 14 PC0 + PB6 PE Paper Error 12 20 PC1 SEL Select 13 13 PB5 /AUTOFD Auto Feed 14 12 PB4 /FAULT 15 9 PB1 /RESET 16 8 PB0 /SELIN Select In 17 10 PB2 The Z8536 INT line (pin 24) is wired to PB7 (pin 15).

cpi first appeared in NetBSD 5.0.
AUTHORS
The cpi driver was written by Hauke Fath <hauke@NetBSD.org>.
CAVEATS
The Hurdler CPI Nubus card does not use a TTL buffer to drive the paral- lel interface. Instead, the card's Z8536 CIO drives the printer port directly. Printers terminating the parallel interface with less than 2 kOhms may cause permanent damage to the Z8536 CIO. NetBSD 5.1 May 18, 2008 NetBSD 5.1
