Have you trying to use the Escape character?

(char)0x1D

i tried prepending an urlencoded escape char (%1B) to a CR char.
No luck... the sms doesn't start.
an escape char only can be sent, but obviously it didn't result in any output in the sms

ok... if i put and urlencoded duble quotes into the sms, the gsm gateway correctly escapes it
Command: gsm send sync sms 2 3929xxxxxx "\"test\"" 10000

if i put a line feed it is not escaped:
Command: gsm send sync sms 3 3929xxxxxx "test

newline" 10000

when you access it through socket in linux, it gives you the a message like:

escape character '^]'

i guess you should do the following:

String cmd = "Command: gsm send sync sms 3 3929xxxxxx \"test"+(char)0x1D+"
"+(char)0x1D+"
"newline\" 10000";

because the escape character is "^]" (Group separator)

you can also try this way:

char GS = (char)29;
