CTRL-Z

Hi

I’m interfacing a gsm modem to my RCM3200 and I need to send AT commands serially from the RCM3200. The command to send sms terminates with CTRL-Z.

Can someone guide me along as to how can I send the CTRL-Z along with the rest of the command.

Thanks.

Use ascii code of Ctrl-Z. It is 26. So just add a char with value = 26 at the end of the message.
