I BOUGHT A TC1000. I,VE GONE THROUGH THE SETUP. I WENT TO MY COMPUTER TO CONNECT THE SERIAL PORT CORD AND THE TC1000 WOULD'NT LET ME CONTINUE I KEPT GETTING THE SAME RESPONSE "TC1000 NOT CONNECTED". I HAVE A LAPTOP AND DESKTOP. AND I GOT THE SAME RESPONSE. I TOOK THE UNIT BACK TO THE STORE AND GOT ANOTHER. AND GOT THE SAME RESPONSE AGAIN. IS THIS JUST DUMB LUCK OR ARE OTHER PEOPLE HAVING THE SAME PROBLEM. I'M PRETTY SURE I KNOW WHAT I'M DOING. COULD SOMEONE GIVE ME SOME INSITE INTO MY PROBLEM. BECAUSE OF THIS I'M CONTEMPLATING GETTING A PRONTO.
