Hi,

I have :

nokia 6610
dku-5 cable
cable driver supporting usb

What happen :

Plugin the cable ... system xp asked for the driver ... installed the driver.
From the device manager i could see that usb cable is redirected to com4.

Using hyper terminal with these command, i could send the sms :

at
at+cmgf=1
at+cmgs="5195155313", 129
Testing sms sending
ctrl + z

But i cannot send sms from vb application. The command are :

MSComm1.CommPort = 4
MSComm1.PortOpen = True
MSComm1.Output = "AT" & vbCr
MSComm1.Output = "AT+CMGF=1" & vbCr
MSComm1.Output = "AT+CMGS=" & Chr(34) & Text2.Text & Chr(34) & ", 129" & vbCr
MSComm1.Output = Text3.Text & Chr(26)


Note : text2 is phone number / text3 is the message / i did not installed sdk 3.0 and pc suite 6.8

What wrong with my vb lines ????? pls help
