In conjunction with that FlightGear has had support for a generic ASCII only input-output protocol handler for a number of years now. It is called 'generic' because it allows handling of just about any information in any form by altering a user modifiable xml configuration file. The functionality has been extended further by the possibility to define an offset and a multiplication factor. This approach might not cover every possible scenario but it will probably be good enough for most cases. | In conjunction with that FlightGear has had support for a generic ASCII only input-output protocol handler for a number of years now.

The data will be tightly packed in a packet that contains the requested data described in the configuration file. Supported types are: boolean values (8-bit), integer values (32-bit), floating point values (32-bit) and double precision floating point values (64-bit). Anders also added the option to support network byte ordering (big-endian) or system native byte-ordering which will save some processing time when only one type of system is used. To make it easier to see how the packet will be handled by FlightGear a utility called generic-protocol-analyze has been created which can be found in FlightGear/utils/xmlgrep. It outputs the data offset and size along with it's description. | ||
