Модуль TP6.0 для управления сигналом DTR (Data Terminal Ready) модема плюс две утилиты для работы с DTR.
A Turbo Pascal 6.0 unit for DTR control plus a little utility to drop or raise DTR plus a utility that will hang up the modem, by dropping the DTR.


1. Included in the archive: DTRCTRL.PAS A Turbo Pascal 6.0 unit for DTR control with DTRCTRL.TPU sources so you can compile this with another version of Turbo Pascal DTR.PAS A little utility to drop or raise DTR with Turbo DTR.EXE Pascal sources HANGUP.PAS A utility that will hang up the modem, HANGUP.EXE by dropping the DTR, pausing and raising the DTR 2. Usage of the DTRCTRL unit: Two functions can be used in this unit: - DTRControl (COMPort: Byte; DTR: Boolean); You just have to specify for which COMPort you want to change the DTR State, and the DTR option is: TRUE = Raise DTR, FALSE = Drop DTR - DTRState (COMPort: Byte); Returns TRUE if the DTR of the specified COMPort is ON (Raised) and FALSE if the DTR is OFF (Dropped) 3. Other programs in the archive: You can get the information about their usage by typing the name of the EXE file without specifying any parameter. 4. Specifications: If you want to use the DTR as a hangup utility, you have to configure the modem so when the DTR is off, it hangs up. With lots of modems, you configure it by typing: AT &D2. 5.
