Dtdrv is the Delphi 4 version of the Tdrv test program. See Testing with Tdrv for details on Dtdrv's features and operation.
Dtdrv is distributed as a complete Delphi 4 project consisting of the following files:
| Dtdrv Project Files | |
|---|---|
| Dtdrv.dpr | Program entry point. |
| Dtdrv.dof Dtdrv.cfg Dtdrv.res |
Delphi 4 project files. |
| Dtdrv.pas Dtdrv.dfm |
Main Dtdrv form. |
| DtdrvAbout.pas DtdrvAbout.dfm |
About Dtdrv form. |
| DtdrvTdat.pas DtdrvTdat.dfm |
Test data form. |
| DtdrvText.pas DtdrvText.dfm |
Text box form. |
| Hex.pas | Hex format and byte conversion routines. |
| Statistics.pas | Statstics formatting routines. |
| Status.pas | Status Report formatting routines. |
| Tdat.pas | Test data frame handling routines. |
| Using.pas | Using Dtdrv text access routine. |
| Vtx.pas | Verified transmission (Vtx) frame handling routines. |
The Dtdrv project also uses Laygo.pas and X21bis.pas.
Just double-click Dtdrv.dpr to load the project into Delphi 4.
Dtdrv.dpr contains the program Dtdrv; directive where
program execution begins.
By default, the Dtdrv project contains the command-line arguments:
stack6.cfg x21loop.cfg
This instructs Dtdrv to use the LayGO hardware emulation driver in loopback mode. You can change which configuration files are loaded by editing the Parameters field on the Local property sheet in Delphi 4's Project → Parameters... dialog.
