We are a DEC VAR in Greece and we want your assistance on a subject
concerning Digital UNIX. Spefically we installed a month ago a DEC
AlphaServer 1000A 5/333, running Digital UNIX v4.0b, to one of our most

important customers. On this system we have installed Microfocus Cobol OSX
server v3.2. The AlphaServer is connected to an Ethernet LAN, and the users
connect to the system from PCs running some of them DOS and other
MS-Windows 95, with Esker's TUN Emul. The emulation we use is ansi.
The problem is with some keys, especially End and shifted function keys.
Also there is a problem with color attributes, which do not appear
normally, instead they appear as black and white. Also blink text is
displayed as not blinking. I tried several emulators, but they have the
same behaviour.
The previous application server our customer has been using was a PC server
running SCO UNIX 3.2v4. On that system there was no problems like those I
have described above. I tried to use the ansi section from SCO's
terminfo.src on DEC Alpha, but there is no improvement.

We would appreciate your prompt on these problems.

Best Regards

Subj:	RE: Keyboard mapping issues.

Christos,

I am not sure if you sent your request to other than the 
[email protected] email address.  Our service is for members of 
Digital's ASAP Program (our support for ISVs program), which I am not able 
to find you being a member of.

We help software developers regarding issues they are having with 
porting/migration and optimization issues on the Alpha platform.  
We do not typically provide product support type issues, as you have asked.

The environment of PCs running terminal emulation software into an 
AlphaServer running Digital UNIX is something we do all the time, so I
certainly do not understand what issue you are having.  I assume you are
running your emulators in VT100 mode?  And that you have an appropriate
/usr/share/lib/termcap for the emulator?  It makes sense that the SCO
box (an Intel PC) would behave a bit better out of the box than the Alpha,
since the Alpha is expecting to have a VT100-style terminal and keyboard 
connected.

I can't understand how the terminal color setup can possibly be due to the
Alpha system.  I would expect this to be on the emulator program setup on
the PCs.  Maybe I am not understanding the color issue, and the complete
program environment.

Can you tell me which terminal emulators you have tried?  I am running an 
internally developed emulator at Digital with no issues.  I am going from an 
Alpha PC (with PC style keyboard), to AlphaServers all the time.  If we
have one of the same (KEAterm for example), I could ask our system operator
to see if things look fine for him.

One thing to note, is that on the PC keyboard (mine at least), the end key 
maps to the "previous" key from the LK201 (classic VT100) keyboard.  The
terminal emulator will send the ASCII sequnce for that key, and Digital
UNIX will interpret it in that fashion (ie: like the "previous" key, and
not the "end" key as it is written on a typical PC keyboard.  If this is the
source of the issue, maybe you can acheive the desired results using the
"dxkeycaps" and "xmodmap" programs supplied with Digital UNIX.  You'll have
to know a bit about the ASCII modes you want to send, etc.

Christos -- as I said, since you are not an ASAP member, we cannot officially
support you, and the question you are asking is not in our charter to support.
Unfortunately, the issue may be complex which would require having the same
setup as you have, also something we could not likely do for you.

Please tell me whether the above regarding dxkeycaps and xmodmap get you 
any further to a solution.  Our operations person will not be able to look 
at this until Monday at the earliest (it is the weekend just about now).
If you have a Software Service agreement, you can call the Customer Support
Center, and see if they can connect you to a group which you can have
consult to you on this.

Regards,

Jeff Kenyon
