Can't send newline

[Ariel Frailich]

Greetings!

I'm trying to send a string to the modem from a script, using <screen  
-S myscreen -X stuff "string%n">. The problem is that I can't get the  
newline character across: it just echoes exactly as I send it. I've  
tried ^m, ^M, %n, %r, \015 and various other octal characters, but to  
no avail.

Just to be clear: I have two terminal windows, one is running screen,  
the other has a command line. If I type <screen -S myscreen -X stuff  
"ATH0%n"> at the command line, the other windows shows <ATH0%n>;  
nothing is sent to the modem unless I press return in that window.  
The same is true for all other newline variations. I tried everything  
I found on this list that worked for others, but none of it is  
working for me (e.g., the thread on sending an ESC across, even using  
<screen -S myscreen -X stuff `echo -ne '%n'`>).

I'm running screen 4.00.02 (FAU) 5-Dec-03, on an iMac Core Duo with  
OS X 10.4.6. Am I doing something wrong? Does screen work differently  
on a Mac? Am I misunderstanding something?

Thank you very much for any help, info, advice, etc.
