Here's another quick piece of software I wrote in a couple of minutes. I popped open VB6 and used MSComm for easy serial communication control.

Here's an example of opening a serial port , setting the properties, and sending out the decimal value of a text box.

MSComm1.PortOpen = True

MSComm1.CommPort = 4

MSComm1.Settings = "2400,n,8,1"

MSComm1.Output = Chr$(txtBox.Text)

This Serial Terminal program made it really easy to debug the RF Juggling Pins. I set up macros also, so I could test out my serial scheme. For example, for my juggling pins I used the following packet type : Start, Address , Data , Checksum. So for instance, a macro for sending out a packet.

MSComm1.Output = Chr$(55) ' Start byte

MSComm1.Output = Chr$(txtAddress.Text) ' the address

MSComm1.Output = Chr$(txtBox.Text)

MSComm1.Output = Chr$(txtBox.Text + txtAddress.Text)
