That should be <cr> (ASCII character 13 decimal) only, without a
<lf>.  Sorry to be pedantic, but with some modems and AT commands
this difference is absolutely critical.

AT commands are terminated with a single character, which is the
ASCII representation of the value stored in the modem's S3
register.  This is always 13 decimal by default.
