OK
-Now uses both smd11 and smd7 for separate AT streams
-smd11 is linked to ttyOUT
-smd7 is linked to ttyOUT2
ttyOUT is intended for automated AT commands (for parse scripts, etc)
ttyOUT2 is intended for manual user initiated AT commands; the new atcmd bin is now linked to /bin as well for utilization of ttyOUT2 by shell. Just type the command atcmd to run it.
Separating these streams will improve responsiveness and help the progress of more development.
