Can anyone give me or point me to an example of controlling the radio transmitter from VB. Preferably using the Open "Com1:" method opposed to the MSComm control as I do not have it. Simply being able to send a beep, in either AM Low or High tone is what I need. Please help me. |

You're not going to be able to use either of those methods, I'm afraid. Iirc, the circuit relies on the computer switching the oscillator on and off at an audible frequency, thus generating the buzzing you hear. You may need to look in to using a "raw IO" dll for VB, so you can talk directly to the hardware and use a Timer control to toggle the oscillator on and off. |
