TimeoutTimeout
Specified in units of 100ms, with a
default of 100 (10seconds).
A value of 0 means no timeout
enforced.
The timeout sets the maximum time to wait
to receive an answer.
If the timeout expires, the exchange
terminates in error with an error code
(CommError = 01hex). If the system
receives a response after the timeout
expiration, this response is ignored.
