Send SMS through mobile phone connected to PC from PowerShell

Hi,
i have one problem. I don't know, how to send a SMS with connected mobile
phone to serial port. I know related AT commands how to do that from
HyperTerm (AT+CMGF=1 and AT+CMGS="PHONE_NUMBER"), but i don't know how to
implement it into PowerShell script. I tried something, but without results...

$port= new-Object System.IO.Ports.SerialPort COM9,19200,None,8,one
$port.Open()
$port.Write("AT+CMGF=1")
Start-Sleep -seconds 3
$port.Write("AT+CMGS=PHONE_NUMBER")
Start-Sleep -seconds 3
$port.Write("Hello, This is my test message")
Start-Sleep -seconds 5
$port.Close()

Thanks for reply.

command; e.g. try:
where `r = CR, `n = LF; If this still doesn't work verify some simple
hayes commands first, e.g. ati0 or ati1 , for product code and
firmware checksum respectively. And finally, even though this is most
likely not the problem, try a lower speed - even 1200bps would suffice
for comms of this nature.

If you want to use events instead of sleeps to read data when it's
waiting, check into my PowerShell Eventing project up on www.codeplex.com/pseventing
; I believe someone is doing something similar with reading a UPS
status via a serial port.

Hope this helps,

Hi Oisin,
thanks for reply, but still not works...

clear
$port= new-Object System.IO.Ports.SerialPort COM9,1200,None,8,one
$port.Open()
$port.Write("AT+CMGF=1`r`n")
Start-Sleep -seconds 3
$port.Write("AT+CMGS=+1234567890`r`n")
Start-Sleep -seconds 3
$port.Write("Hello, This is my test message`r`n")
Start-Sleep -seconds 5
$port.Close()

I tried ati0 and ati1, from terminal it works, but i don't know how to read
output from command to console.
Do you have any other idea, where the problem should be?

I found on net syntax for "AT+CMGS" command, phone number must be in
"quotes", but i don't know how to write it into the script. Maybe there is
the problem, why id doesn't work.

Help please. PaoloS.
