GPIB-232CT-A for MS-DOS/Windows
As specified by MS-DOS, the device name cannot use the following
characters:
.
"
/
\
[
]
:
|
<
>
+
=
;
,
(ASCII characters less than hex 21)
and cannot use the following reserved names:
CON
NUL
Uppercase and lowercase letters are treated the same. The string
PLOTTER
is treated the same as the string
plotter
, for example. For this reason,
IBCONF
maps all lowercase letters to uppercase.
Caution: In DOS, devices must not have the same names as files,
directories, or subdirectories. The MS-DOS GPIB device
driver uses the names
GPIB0
,
GPIB1
,
GPIB2
,
GPIB3
and
DEV1
,
DEV2
,
DEV3
through
DEV32
. If you have files,
directories, or subdirectories with one these names, you must
rename them.
The string representing a device or access board name is the first variable

application program. Refer to Chapter 4, NI-488.2 Software Characteristics
and Routines, and Chapter 5, NI-488 Software Characteristics and
Functions , of the NI-488.2 Software Reference Manual for MS-DOS for
more explanations of
ibfind
.
