118.0. "VTs compabitlity" by LISVAX::RIBEIRO_N (NELSON RIBEIRO @XIP) Thu Jan 30 1997 12:42

I costumer has logged me a call with a problem of compability between an VT420
and a VT520 on VT100 mode.

According to the costumer when he presses a certain key (DO key) within an
application that is running on a WANG system (the WANG system is prepared to
emulate VT100 compability)with a VT520 everything works fine but with a VT420
when he presses the same key (DO) the layout of the application goes "crazy" and
messes up the screen.  

I don't known if this is the right conference or not, but if it isn't can
someone point me out the right one, please?

Thanks,
NelsonR.

    You may be dealing with 7-bit vs 8-bit char setups or almost anything
    else, really. Try ATLANT::TERMINALS.
118.2<DO> is <ESC>[29~XDELTA::HOFFMANSteve, OpenVMS EngineeringThu Jan 30 1997 13:1828
   The terminals group was sold to Sun River...  The other groups to
   contact are the application support vendor and/or Wang.

   Use the <display|interprete controls> and the <local echo> options
   in the terminal's set-up to determine exactly what character sequence
   is being generated when the <DO> key is pressed on each terminal.
   As was mentioned, make sure the other set-up attributes are compatible
   between the working and non-working terminals -- 7 vs 8 bit characters,
   etc.

   The expected seven-bit sequence generated by the <DO> key (also known
   as the <F16> key) is "<ESC>[29~".  (This sequence is one of the many
   ANSI standard escape sequences...)

   The "<ESC>[29~" sequence can be generated manually via "<CTRL-[>[29~",
   meaning you can generate this sequence from most any terminal...

    Note also that <ESC>[ has an 8-bit equivalent viz. <CSI>.
    
    Verify that the two terminals are emulating the same VT model i.e.
    either VT400 or VT500 could be emulating VT52 (maybe), VT100, VT200,
    VT300.
    
    Check that parity, start bits, stop bits, frame are the same on the two
    terminals.
    
    Put an RS232 line analyser on the line.
