You can use alternate keystrokes to control the DCUI over a serial port. This is useful when F2 or other function keys cannot be used.

Alternate keystroke mappings for DCUI mode:

Esc + 1 -> F1

Esc + 2 -> F2

Esc + 3 -> F3

Esc + 4 -> F4

Esc + 5 -> F5

Esc + 6 -> F6

Esc + 7 -> F7

Esc + 8 -> F8

Esc + 9 -> F9

Esc + 0 -> F10

Esc + ! -> F11

Esc + @ -> F12
