[kscorpiot]

Hi I'm new at trying to send SMS through visual basic, however i'm not sure where i have gone wrong. This is the code i have written, but i have no response at all neither from the PC nor the Phone. Can anyone please help Thanks!!

MSComm1.CommPort = 1
MSComm1.Settings = "9600,N,8,1"
MSComm1.InputLen = 0
MSComm1.PortOpen = True

MSComm1.Output = "AT" & Chr$(13) & Chr$(10)
MSComm1.Output = "AT+CMGF=1" & Chr$(13) & Chr$(10)
MSComm1.Output = "AT+CMGS=" & Chr$(34) & "+6590906653" & Chr$(34) & ",129" & Chr$(13) & Chr$(10)
MSComm1.Output = "test" & Chr$(26) & Chr$(13) & Chr$(10)

Hi! Did u ever resolve the problem? I got stuck here too. I think the problem is that we need to send a 'ctrl+z' command to the modem, but I can'n seem to figure out how.
