In order to allow customers to implement simple ASCII protocols without having to ask B&B
Electronics to develop custom drivers, Fieldbus Gateway Manager provides a new facility
whereby the software’s programming language can be used to directly control either serial
ports or TCP/IP network sockets. Note that if you are not using custom ASCII protocols, but
are instead using the standard drivers provided with Fieldbus Gateway Manager, you can skip
this section.
