Check the status of a BTS timer.

CHECK TIMER
>>-CHECK--TIMER(data-value)--STATUS(cvda)----------------------><
Conditions: INVREQ, IOERR, TIMERERR
Description
CHECK TIMER returns the status of a BTS timer. It allows the requestor
to discover whether a timer has expired and, if so, whether it expired normally
or whether its expiry was forced by means of a FORCE TIMER command.
On return from this command, if the timer has expired its associated event
is deleted from the current activity's event pool.
The only timers a program can check are those owned by the current activity.
