2.3.7.4 Timed Button J1B1 (+/- J2B1) Response (#M)

The Timed Button J1B1 (+/- J2B1) Response command pauses Cogsys execution until gameport button J1B1 is pressed (alone or with J2B1). If J1B1 is pressed, the key `A' is written to output with the response time. If J1B1 is not pressed within the specified time limit, '&' is written to output with the time limit.

System:

Waits up to timelimit milliseconds for J1B1 (+/- J2B1) to be pressed. Then writes response to output. Cogsys variable 7 (COGVAR_KEY) is updated with the key pressed. Cogsys variable 5 (COGVAR_TIME) is updated with the reaction time.

Output:

The character `A' with the response time is written to output. If the timelimit limit is reached before J1B1 is pressed, '&' is written as the key pressed, and timelimit as the time.
