The keyboard for a 7035 series terminal contains only a limited number of keys. Keyboard remapping allows you extend the number of characters that can be produced by the keyboard. For example, it allows you to remap the "A" key to a Greek alpha. When the default map is in effect, pressing "A" will give you "a" but when the remap keyboard is in effect, pressing "A" gives you "a". Almost any key and some key combinations can be re-mapped to any Unicode character.
This remapping feature only works at the TekTerm level (it cannot be used in DOS). A data file named keyboard.map is downloaded into the terminal (details below). The remapping functionality is toggled on and off. On start-up the default keyboard map is used. Once the toggle sequence (Alt-K) is entered the remapped keyboard will be used and will remain in use until the toggle sequence is entered again. All Unicode values for remapped characters are converted to the configured character set before being sent to the host. If the Unicode value associated with a key cannot be converted to the host character set, an error beep will sound and the key is ignored.
The map uses the following format:
0x<scan code> 0x<character code (ASCII)> U+<remapped character (Unicode)>
0x1E 0x41 U+03B1 \# This will map capital letter a (A) to Greek small letter alpha (a).
0x68 0x00 U+03A3 \# This will map Alt-F1 to Greek capital letter sigma (S).
The following hardware and software is needed to remap a 7035 series keyboard:
Make a copy of the template file "keyboard.map" and rename it to something else.
Edit the keyboard.map file
Load the keyboard.map file on the terminal.
