Using VB to make a terminal program (with a bit of a twist)

Hello all,
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 = "!"
End Sub

Private Sub Form_Load()
MSComm1.RThreshold = 4
MSComm1.CommPort = 1
MSComm1.OutBufferSize = 1
MSComm1.PortOpen = True
recvdata = False
End Sub

Private Sub MSComm1_OnComm()
If MSComm1.CommEvent = comEvReceive Then
Text1.Text = Text1.Text + MSComm1.Input
End If
End Sub

Private Sub Form_Unload(Cancel As Integer)
MSComm1.PortOpen = False
End Sub
=================

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,
Aaron Tufgar

Actually I found the answer just had to enable CTS.  Found this answer in the archives.  :)
