Re: DOS Box Keyboard problem

<quote>
One or more CON code pages invalid for given keyboard code
The KEYB command examined all prepared code pages, and has found that at least one code page is incompatible for your screen console device (CON). This is only information to let you know that your keyboard and screen console are working with different code pages.

chcp displays or sets the active code page number.

Open command.com...
Start | Run | Type: command | Click OK |
Type: chcp hit Enter.

You get...
Active code page: nnn

Type: exit and hit Enter to close command.com.

Open cmd.exe...
Start | Run | Type: cmd | Click OK |
Type: chcp hit Enter.

You get...
Active code page: nnn

Are they the same?

For U.S. English versions of Windows NT the default is 437 codepage, U.S.
English.

Active code page should be the same for both command.com and cmd.exe.

Check this registry key and entries.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\CodePage]
"ACP"="1252"
"OEMCP"="437"
"MACCP"="10000"
"OEMHAL"="vgaoem.fon"

ACP is the default ANSI code page; OEMCP is the default OEM code page; and
MACCP is the default Macintosh code page.

The OEMCP value controls to which OEM code page to translate ANSI, and the
OEMHAL value controls the display of extended characters at a command
prompt.

ANSI Codepage ID 1252 is used for all Western European languages, including
English.

The default OEM code page in Windows NT is the DOS 437 code page.

codepage select= yyy

yyy value from table.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Control\Nls\CodePage

Here's some info from various sources.

ACP is the default ANSI code page; OEMCP is the default OEM code page; and
MACCP is the default Macintosh code page.

The OEMCP value controls to which OEM code page to translate ANSI, and the
OEMHAL value controls the display of extended characters at a command
prompt.

the default OEM code page in Windows NT is the DOS 437 code page

The computer's ANSI code page is stored in the following registry value:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\CodePage\ACP

For U.S. English versions of Windows NT, Windows 95, and Windows 98, the
default OEM code page is 437 (U.S. English). The computer's OEM code page is
stored in the following registry value:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\CodePage\OEMCP

To verify the client OEM code page on Windows NT, Windows 95 and Windows 98
computers, run chcp from the command line. To verify that data in a file is
stored in the proper code page, you must use the appropriate editor. ANSI
data should look correct in any GUI editor (such as Notepad, WordPad, or
Microsoft Word). OEM data should look correct in a command-line tool (such
as type or edit).

In news:B3CF240E-73C5-458E-A513-4F56E0132BDB@xxxxxxxxxxxxx,
Pandora <Pandora@xxxxxxxxxxxxxxxxxxxxxxxxx> hunted and pecked:
When I start any DOS program I get message in the DOS box "One or more CON
code pages invalid for given keyboard code". My DOS program will run but
many keys do not deliver the correct character - all shift characters
deliver strange symbols.

This may be due to the fact I have a portuguese keyboard while XP etc are
all set up in UK English.

Maybe I need to put something in autoexec.nt but what? Keyb seems to have
disappeared under XP.

Any help appreciated.
