Ho uno strumento che permette di indirizzare staticamente e dinamicamente le linee RTS (L-Line) e TXD (K-Line).
Se ci fosse interesse, potrei inviare il documento a un destinatario centrale via e-mail.

Ciao Bert,
Sarei molto interessato/a anche io.

fosse possibile dal punto di vista della licenza, lo passerei a Rainer, nel caso in cui lui volesse/potesse renderlo disponibile per il download. In questo modo, risparmieresti molte email con lo stesso contenuto.[url]
Ciao,
questo problema, ma non dimenticate: [/url]/viewtopic.php?p=10101&highlight=#10101
Codice: |
The EscapeCommFunction function directs a specified communications device to perform an extended function.
BOOL EscapeCommFunction(
HANDLE hFile, // handle to communications device
DWORD dwFunc // extended function to perform
);
Parameters
hFile
Handle to the communications device. The CreateFile function returns this handle.
dwFunc
Specifies the code of the extended function to perform. This parameter can be one of the following values: Value Meaning
CLRDTR Clears the DTR (data-terminal-ready) signal.
CLRRTS Clears the RTS (request-to-send) signal.
SETDTR Sends the DTR (data-terminal-ready) signal.
SETRTS Sends the RTS (request-to-send) signal.
SETXOFF Causes transmission to act as if an XOFF character has been received.
SETXON Causes transmission to act as if an XON character has been received.
SETBREAK Suspends character transmission and places the transmission line in a break state until the ClearCommBreak function is called (or EscapeCommFunction is called with the CLRBREAK extended function code). The SETBREAK extended function code is identical to the SetCommBreak function. Note that this extended function does not flush data that has not been transmitted.
CLRBREAK Restores character transmission and places the transmission line in a nonbreak state. The CLRBREAK extended function code is identical to the ClearCommBreak function.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.

The SetCommBreak function suspends character transmission for a specified communications device and places the transmission line in a break state until the ClearCommBreak function is called.
BOOL SetCommBreak(
HANDLE hFile // handle to communications device
);
Parameters
hFile
Handle to the communications device. The CreateFile function returns this handle.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.

Nel caso in cui dovessero sorgere problemi con la licenza, posso (se avrò tempo) creare io stesso un piccolo programma che risolva il problema.
Windows offre le seguenti funzioni API a questo scopo:
