Echo

This argument controls whether a screen echo is displayed or not. You can only echo alphanumeric keys from the standard PC-keyboard.

0 No screen echo

1 Display screen echo as defined by a previous SE-trial command or SETECHO-session command. Each keystroke is stored in separate result columns (Rn and Kn).

2 Same as 2, but entire string input is stored in one response column. Only the latency of the first character input is recorded. Note, that string will always be listed in upper case.

The echo mode activates a simple editing function where the Skey can be used to delete characters. Editing and deleted keys will not be recorded.
