DPCC Domain/OS BSD DPCC
NAME
dpcc - runs the DPCC software
SYNOPSIS
dpcc [options]
DESCRIPTION
The dpcc command starts DPCC in a window on your Apollo workstation.
DPCC consists of a printed circuit board and associated software that
emulate an IBM PC/AT, allowing you to use DOS commands and run PC
application programs. To use DPCC, you must have a DN3000/DN4000
Series workstation as well as the DPCC software and board.
OPTIONS
-c[olor] Runs DPCC in color mode. Running DPCC in color mode
emulates the IBM Color/Graphics Adapter. If you do not
specify this option, DPCC runs in monochrome mode, which
emulates the IBM Monochrome Adapter and the Hercules
display adapter.
-b[oth] Runs DPCC in two windows (dual display mode). This option
lets you use one monitor for text and the other for
graphics.
-nf[loppy] Prevents DPCC usage of the workstation's diskette drive.
If you do not specify this option, DPCC acquires the
diskette drive so that you can use the drive for DOS and
application program diskettes.
-bf[loppy] Runs DPCC in BIOS floppy mode. When you include this
option, DPCC supports only DOS commands and utilities that
access the diskette drive through ROM BIOS. Use this
option if you are unable to start DPCC because of the
extensive paging activity on your node. (You will receive
the error message "Unable to wire buffer for DMA".) When
you specify -bf, you cannot use most copy-protected
applications or any applications that do not access the
diskette drive not through ROM BIOS. If you try to use
such applications after specifying the -bf option, DPCC
displays an error message in the status pane.
-hd[isk] pathname
Uses the specified file as the DPCC hard disk. If you do
not specify this option, DPCC looks for the file
HOME/user_data/dpcc_hard_disk to use as the DPCC hard disk
(where HOME is your login home directory). If this file
does not exist, DPCC uses the file
`node_data/dpcc_hard_disk, which is created when you first
run the DPCC software.
-hd2 pathname Uses the specified file as the second DPCC hard disk. If
you do not specify this option, DPCC looks for the file
dpcc_hard_disk2 in the same directory as the first hard
disk.
-rd -rd2 Indicates that either one or both DPCC hard disks be used
as read-only disks. A read-only hard disk may be shared
with other DPCC users.
-hd_force n Specifies the number of seconds after the last hard disk
write that DPCC waits before force-writing the hard disk.
A value of 0 causes all hard disk writes to be forced; a
very large value causes no hard disk writes to be forced.
If you do not specify this option, the default is 10
seconds.
-nlocking Disables record locking and file sharing code. Use of
this option, when you do not want to restrict file access,
improves product performance.
-start pathname
Uses the specified file as a list of DOS commands that are
executed at DPCC startup (after autoexec.bat executes).
-sio pathname Uses the specified sio device to emulate COM1. The
default pathname is /dev/sio1.
-prn pathname [options]
Uses the specified pathname and options to emulate PRN.
The default pathname is /com/prf.
-alt Uses the default controller, if your workstation contains
two DPCC controllers.
-dev[ices] pathname ...
Uses the specified file(s) as the Device Descriptor File
(DDF) for the IBM PC/AT-compatible add-on board that is
installed in your workstation. DPCC displays an error if
it cannot acquire the devices you have specified in the
DDF. (DPCC includes sample DDFs for add-on boards that are
compatible with COM1 and LPT2 on an IBM PC/AT. The
pathnames of these files are /dev/com1 and /dev/lpt2.)
-version Provides information about the version of Domain/PC
Coprocessor you are running.
EXAMPLES
To start up DPCC in two windows and execute the DOS commands that are
listed in the file /start_spreadsheet in the //bingo directory, use the
following command:
$dpcc -b -start //bingo/start_spreadsheet
To run DPCC in color mode while preventing access to the workstation's
floppy drive, enter this command:
$dpcc -c -nf
LIMITATIONS
Please refer to the Domain/PC Coprocessor Software Release Notes for
a current list of DPCC limitations.
