cygwin /dev/ttyS2: Device or resource busy

Ciao a tutti!!!
il mio problema è questo: sto cercando di inviare dei comandi AT da PC a cellulare utilizzando il bluetooth e cygwin e vorrei visualizzare le risposte nella shell bash. Per farlo apro due terminali utilizzando le seguente istruzioni:

xterm &

Sul primo scrivo

cat /dev/ttyS2

in quanto il dispositivo è collegato alla com3 e questo mi dovrebbe permettere di visualizzare a video i dati che entrano nella porta.
Il secondo terminale invece mi consente di inviare le istruzioni con il comandi AT, ad esempio:

echo "AT">/dev/ttyS2


L'errore che mi si presenta a questo punto è però il seguente:

/dev/ttyS2: Device or resource busy

Qualcuno sa come potrei risolvere questo problema??AIUTOOOOOO
