330.0. "alternative keyboards, how ?" by GOTA1::BJERKEHOLT (Bo Bjerkeholt, SWAS, @GOO) Mon Mar 06 1989 02:05

	I have a customer who makes system for emergency calls center. It 
	is based on VAXes with a Tektronix 4209 for every  operator. 

	To make life easier for the operator they have designed and built
	their own keyboard with lots of functionkeys. 

	Now we are looking for replacing those Tektronix screens with
  	workstations. 

	   How can we connect their keyboard as a replace for the LK201.
	   When they fill in all their forms it is done with an application
	   that is heavily dependent on the features in the terminaldriver.
	   It's extended reads, escape sequence reqognition, field validation
	   etc. You could have it as a test suite for different versions of
	   the TT-driver.
	   In the file DECW$DEVICE.COM the logical DECW$KEYBOARD is set 
	   up. If I redirect this to let say TTA2: on my VS2000 will it
	   mean that I can plug in the extra keyboard and make it look like
	   the input came from my normal LK201 keyboard ? Is still the 
	   keymapping files used ?
	   If this is the case will this functionality remain in the future ?
	   I tried to redirect it and plugged in a VT220 but then
           DECwindows never comes up at all so obviously it didn't work
    	   that easy, maybe something else is needed too.

	Regards,
		Bo

    From my brief tip-toe thru the drivers -- no.  The current DECwindows
    drivers and servers expect a LK201 on the other end.  The only way
    that you might be able to do it is if you wrote a port driver for
    the serial line and massaged the data (both input and command output)
    to make your device look like a LK201.
    

    _Fred (who also would like to feed something other than LK201 matrix
    codes to the drivers).

    If my customer adapt their keyboard to the LK201 matrix, would it
    be possible to have more keys specified?  What is the limit on the
    number of keys (FF maybe?) LK201 keymap files start at 56.
    
    Still don't realize what this logical DECW$KEYBOARD is good for.
