since this is a Wavecom modem, the CM[E|S] ERROR 515 means according to Wavecom 
manual: Pleast wait, init or command processing in progress.

Meaning the GSM modem is currently doing some work in the background and doesn't 
  want to get disturbed by any AT command.

Hence, this is a temporary failure and we should sleep for a retry of the AT 
command.

Did anyone of the smsc_at.c commiteres take this into concideration?
