Hi,

I can use Hyper Terminal to send sms using Infrared. The problem is that when I send, I need to type 2 times. Here is the example:

1- AT+CMGS="+91232538538"
2- > Hello GSM
3- Press Ctrl + Z and Enter

Now I want to use this command in VB. So I want to send only one command the sms will send. I tried this command but it's not work:

AT+CMGS="+91232538538",145<CR>Hello GSM<CTRL-Z>

The problem is that how to send Ctrl-Z in VB?

Please help!

Thank you,
BM.
