6.2.13 Write Bytes Function (4401)
This operation can be used to transmit one or more characters to the remote device
through the specified serial port. The character(s) to be transmitted must be in a word
reference memory. They should not be changed until the operation is complete.
Up to 250 characters can be transmitted with a single invocation of this operation. The
status of the operation is not complete until all the characters have been transmitted or
until a timeout occurs (for example, if hardware flow control is being used and the remote
device never enables the transmission).
