I currently access a remote Unix server which has an external modem connected to one of it's serial ports (/dev/cua/b). At times, this server undergoes a hard reset and for some reason this disallows us from making use of the modem any longer. A hard reset of the modem always seems to fix the... (0 Replies)

lpt
LPT(4) BSD Kernel Interfaces Manual LPT(4)NAME
lpt -- generic printer device driver
SYNOPSIS
device ppc
device ppbus
device lpt
DESCRIPTION
The current lpt driver is the port of the original lpt driver to the ppbus(4) system.
One purpose of this port was to allow parallel port sharing with other parallel devices. Secondly, inb()/outb() calls have been replaced by
ppbus function calls. lpt is now arch-independent thanks to the ppbus interface. See ppbus(4) for more info about the ppbus system.
The parallel port bus is allocated by lpt when the printer device is opened and released only when the transfer is completed: either when the
device is closed or when the entire buffer is sent in interrupt driven mode.
The driver can be configured to be either interrupt-driven, or to poll the printer. Ports that are configured to be interrupt-driven can be
switched to polled mode by using the lptcontrol(8) command.
Depending on your hardware, extended capabilities may be configured with the lptcontrol(8) command. With an ECP/ISA port, you can take
advantage of FIFO and DMA.
In order to retrieve printer info from /dev/lpt0, just apply the cat command to the device. If the printer supports IEEE1284 nibble mode and
has data to send to the host, you will get it.
FILES
/dev/lpt0 first parallel port driver
SEE ALSO ppbus(4), ppc(4), lptcontrol(8)HISTORY
This driver replaces the functionality of the lpa driver, which is now defunct.
BUGS
There are lots of them, especially in cheap parallel port implementations.
It is only possible to open a lpt port when a printer is connected and on-line, making it impossible to run lptcontrol(8) when there is no
printer connected.
This driver could still stand a rewrite.
