missing terminating character error

I am attempting to send an AT command to a GSM modem and I get error "Missing terminating " character" when I try to compile. I am using IDE 1.03 on an UNO. This is the code that creates the error.


I am guessing that the \ is a unique character used for CR and LF so I kind of understand why I get the error. I just cant figure out how to work around it. Any suggestions on how I can send that command?

Try double backslash

AWOL- that worked perfectly, thanks!

Could you please explain why LOL. When you suggested it I really thought it would output "AT\Q0" but it output "AT\Q0" just as I require. How come it drops one of the backslash?

Backslash is the escape character in C.
