DESCRIPTION
The dpcc_remote command starts DPCC-Remote in a window on your Apollo
workstation. DPCC-Remote 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-Remote, you must
have a DN3000/DN4000 Series workstation as well as the DPCC software and
board.
ARGUMENTS
-n[ode] node_spec
Specifies the remote node that contains the DPCC-Remote
board and is running dpcc_server software. The node_spec
is the hexadecimal node ID of that node. (The default is
the catalogued node name.) If you do not know the node
ID, ask your system administrator.
OPTIONS
-c[olor] Runs DPCC-Remote in color mode. Running DPCC-Remote in
color mode emulates the IBM Color/Graphics Adapter. If
you do not specify this option, DPCC-Remote runs in
monochrome mode, which emulates the IBM Monochrome Adapter
and the Hercules display adapter.
-b[oth] Runs DPCC-Remote in two windows (dual display mode). This
option lets you use one monitor for text and the other for
graphics.
-nf[loppy] Prevents DPCC-Remote usage of the workstation's diskette
drive. If you do not specify this option, DPCC-Remote
acquires the diskette drive so that you can use the drive
for DOS and application program diskettes.
-bf[loppy] Runs DPCC-Remote in BIOS floppy mode. When you include
this option, DPCC-Remote supports only DOS commands and
utilities that access the diskette drive through ROM BIOS.
Use this option if you are unable to start DPCC-Remote
because of 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 through ROM BIOS). If you try
to use such applications after specifying the -bf option,
DPCC-Remote displays an error message in the status pane.
-hd[isk] pathname
Uses the specified file as the DPCC-Remote hard disk. If
you do not specify this option, DPCC-Remote looks for the
file HOME/user_data/dpcc_hard_disk to use as the DPCC-
Remote hard disk (where HOME is your login home
directory). If this file does not exist, DPCC-Remote uses
the file `node_data/dpcc_hard_disk, which is created when
you first run the DPCC-Remote software.
-hd2 pathname Uses the specified file as the second DPCC-Remote hard
disk. If you do not specify this option, DPCC-Remote
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-Remote hard disks
be used as read-only disks. A read-only hard disk may be
shared with other DPCC-Remote users.
-hd_force n Specifies the number of seconds after the last hard disk
write that DPCC-Remote 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.
-start pathname
Uses the specified file as a list of DOS commands that are
executed at DPCC-Remote 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 alternate controller if the node running the
dpcc_server software contains two DPCC-Remote controllers.
-dev[ices] pathname ...
Use the specified file(s) as the Device Descriptor File
(DDF) for the IBM PC/AT-compatible add-on board installed
in the node running the dpcc_server software. DPCC-Remote
displays an error if it cannot acquire the devices you
have specified in the DDF. (DPCC-Remote 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 Remote you are running.
EXAMPLES
To start up DPCC-Remote in two windows and execute the DOS commands that
are listed in the file start_backup in the //fuji directory, use the
following command:
$dpcc_remote -b -start //fuji/start_backup
To run DPCC-Remote in color mode and use the file my_disk in the
//tiger/joe directory as the DPCC-Remote hard disk, use this command:
$dpcc_remote -c -hd //tiger/joe/my_disk

a current list of DPCC-Remote limitations.
