I'm trying to tie-down the final logic in a VT320 terminal emulator I've written, and am getting conflicting notions of how the National Replacement Character Sets are used.. Anyone own up to understanding this? :) The basic understanding problem i have is how the "hardware" keyboard type and the selection of "software" Character Sets in G0-G3 interact. From what i understand, the input side of translation always is hardwired to the current hardware keyboard type, setup in the NVRAM of the DEC terminal. So there is always the twelve character remapping "statically" done on the input side, independent of application software. Assuming this is true, the question is the effect of Character Set selection for G0 thru G3 on the output side, and how this affects what appears on the screen. And what is the default output when going into NRCS mode (<ESC>?42h) with all this.. Anyone out there understand all this? If so please send some email to enlighten me, thanks a lot! -jim -- -Jim Becker / jcb@pcx.ncd.com / Network Computing Devices, Inc. (NCD) -- --
