UDP Support
The P3 port can be used to transfer an ASCII representation of the converter's settings between
the Converter and a host computer.
The transfer uses a simple ASCII file structure and XON / XOFF protocol. This is provided by
most communications packages. Host computers tested include IBM PCs XT/AT, running both
Windows and MSDOS, Psion Organiser 3 and many more.
Transferring data from the Converter to a host computer is defined as “Downloading” ,whereas
transferring data from a host computer to the Converter is defined as “Uploading”.
Refer to Chapter 6: “Programming Your Application” - P3 SETUP for parameter details.
