[Function] Set the timeout to be applied to a READ command.

The timer setting specified in operand 1 will set the maximum time the program will wait for the

character string read to end when a READ command is executed.

If the end character could not be read before the timer is up during the execution of the READ

command, a timeout will occur and the program will move to the next step.

(Whether or not a timeout has occurred can be checked from the return code that will be stored in a

local variable immediately after the READ command is executed.)

If necessary, specify the processing to be performed when a timeout occurs.)
