I'm not a termcap expert but don't you simply need a PC TERM (scan code) type terminal like a wyse 60 to capture all those codes? You need the keyboard with all those functions plus ALT anyway, right? After all WORD uses ansi termcaps entries and works fine on both a PC console and a wyse 60 PC keyboard. Besides, in our own applications we use function keys on even non-scan code terminals - all with termcaps. I'm sure more could be done in that direction. >> As for video, aren't you still stuck with dumb terminals as the >> main limitation?

I'm trying to think if they really do these things on a TV950 for instance. I don't think so. Only certain terminals with certain hardware qualifications make the grade into functionality. I also think that they use the scan code or PCTERM type emulation just like ms word. >The problem is we need to port an application that is already running >under DOS with a *very* specific user interface to Unix. We need the >advanced video and keyboard functions. And I'm sure you'll find that a monitor does not make a dumb terminal look like it. There are solutions to the problem by using inexpensive PCs as terminals under various emulation facilities or something like Sun River under optics. Price wise there is not much difference anymore. So if you need DOS tools and are not yet ready to climb to MOTIF it is perhaps best to stay there as the worlds are not quite yet the same. Fred -- W.
