I'm controling a modem with a microcontroller and I'm now using a terminal program called Creative Communication Terminal Emulator to display the data.
Here's what happens:
1. The microcontrollers modem dials another modem and they connect.
2. I type a "!" into the terminal.
3. The microcontroller recieves this character and outputs a string.
Everything works fine in the terminal program. I can see the return string.
However I made a program in VB and I can not see the return string. The microcontroller does recv the ! and return a string but nothing is outputted in a vb text box.
Here is my code:
Private Sub Command1_Click()
MSComm1.Output = "!"
Private Sub Form_Load()
MSComm1.RThreshold = 4
MSComm1.CommPort = 1
MSComm1.OutBufferSize = 1
MSComm1.PortOpen = True
recvdata = False
Private Sub MSComm1_OnComm()
If MSComm1.CommEvent = comEvReceive Then
Text1.Text = Text1.Text + MSComm1.Input
Private Sub Form_Unload(Cancel As Integer)
MSComm1.PortOpen = False
Why can I not see the string from the microcontroller from my program when I can see it from the terminal program??
Thanks in Advance,
