Overview of the RS-232C Serial Interface
Serial interface programming techniques are similar to most general I/O
applications. Refer to the programming language documentation for more
information on how to initiate the card and verify the status.
Due to the asynchronous nature of serial I/O operations, special care must be
exercised to ensure that data is not lost by sending to another device before the
device is ready to receive. Modem line handshaking can be used to help solve this
problem.
Settings for the Serial Interface
Refer to the documentation on your computer, programming language, and I/O
card to configure the serial bus.
The serial port is not programmable but manually set. The default settings at preset
and other choices are as follows:
