fix: smkx keypad-transmit mode #367

Closed ldez closed 2 years ago

ldez commented 2 years ago

To see the difference between normal/application modes, consider this example:

  • In normal (non-application) mode, the terminal transmits a down-arrow as \E[C, which happens to echo as a down-arrow.
  • In application mode the terminal transmits \EOC, which echoes as C. That is because the \EO is the SS3 control, which says to use the character from the G3 character set for the next cell.

ESC = Application Keypad (DECKPAM).

ESC > Normal Keypad (DECKPNM), VT100.
