John:
 
It appears the following code is the culprit:
 
      tclCMD[CharLoc,1] = KeyStr
      CRT KeyStr :
 
When it was replaced by:
 
      tclCMD1 = tclCMD[1,CharLoc-1]
      tclCMD2 = tclCMD[CharLoc+1,9999]
      tclCMD  = tclCMD1 : KeyStr : tclCMD2
      CRT KeyStr :
 
...the problem mostly went away, although it does still occasionally occur.  How
weird?!

The usual candidates: 

 UDT.OPTIONS 109 ON (Telnet nodelay) for input 

Otherwise the likely candidates are: 

1. VPN tunnel configuration 
2. WAN network configuration 
3. Any contention on the TELNET port? (change it from port 23 to something else 
and
see). 
4. (maybe) Broadcom NIC and driver combination 
5. Dell management software 

True test: 

Open a DOS session on the CONSOLE (to localhost) and see if you have the 
same problem. If you are LOCAL and on the CONSOLE and have no problem then 
it's not UniData - it's something else. At that point it's a matter of 
elimination. 

At that point I'd try Microsoft Telnet and see if the problem exists there as 
well. 

Hope this helps.....

I use a subroutine to manage all data input for a character based version of 
our 
application... 
  
This has worked flawlessly for 10-15 years.  We moved a group of our clients 
from D3 
to UniData v7.1.9 on a new Dell Win 2K3 machine.  Since then, we've been having 
problems with the data input code, in that UniData seems to be dropping 
characters. 
An example is in our ECL shell program we might enter something like:

...Welcome to 'TCL'.  Enter Command to execute, or Press [Esc] to exit.

Does anyone know if the SYSTEM(14) function, or the type-ahead buffer, can be 
controlled (configured).  The code that runs this looks like: 
  
LOOP                                                              ; ** UD 
version 
   IF NOT(WaitTime) THEN                                          ; ** UD 
version 
      INPUT AsciiChar,1: UNFILTERED     ; ** get a raw byte            UD 
version 
   END ELSE                                                       ; ** UD 
version 
      INPUT AsciiChar,1: FOR WaitTime UNFILTERED THEN             ; ** UD 
version 
         NULL                                                     ; ** UD 
version 
      END ELSE                                                    ; ** UD 
version 
         IF I.VALUE = NULL$ THEN I.VALUE = WCHAR                  ; ** UD 
version 
         AsciiChar = CHAR(13)                                     ; ** UD 
version 
         MenuExit  = 1                                            ; ** UD 
version 
      END                                                         ; ** UD 
version 
   END                                                            ; ** UD 
version 
   DecChar  = SEQ(AsciiChar)            ; ** convert to decimal        UD 
version 
   HexStr  := OCONV(AsciiChar, 'MX')    ; ** convert to hex            UD 
version 
   DecStr  := DecChar : SP1             ; ** build decimal string      UD 
version 
   KeyStr  := AsciiChar                 ; ** build ascii               UD 
version 
UNTIL NOT(SYSTEM(14)) DO REPEAT                                   ; ** UD 
version 
  
Any thoughts would be appreciated.
