Comms program

Anyone attempting this project will have to have a detailed knowledge of DXF file formats. The attached comms program, similar to hyperterminal, has a number of glitches and minor software bugs.? The programmer has disappeared.? We don't have the source code.? We require someone? to? 1.? de-compile it to the source code 2. fix one of the main bugs in it: ? ? ? ? ? ? ? ? When the software receives the data from the external source it gives PointNumber, X-Coord, Y-Coord, Z-Coord, Point Code.? When we do a transformation to DXF format using the TS-Com0 software (Transform>NEZ SurveyData and CASS Coordinate->DXF) the software does a successful transform but when the DXF file is opened in Autocad Design TrueView I get the following error message: " Syntax error or premature end of file on line 236. Invalid or incomplete DXF input -- drawing discarded." Line 236 is where the point code occurs in the DXF.? We require this error to be fixed. 3.? put another feature in the software: ? ? ? ? ? ? ? ? ? When the software does a CASS Coordinate -> DXF transform, it should put the points that have different codes on different layers.
