У нас немного по другому:

void init()
{
   ...
   sc = new ComPortMSComm();
   sc.initParmDefault();
   ...
}
void GetBarcode()
{
    Barcode   input;
    ComVariant          res;
    str 1               ch;
    int                 i, template;
    ;

   i     = sc.InBufferCount();
   input = "";

   if(i)
   {
            sleep(50);
            i = sc.InBufferCount();

            while(i > 0)
            {
                res   = null;
                ch    = "";
                res   = sc.Input();
                ch    = res.bStr();
                input = input + ch;
                i     = sc.InBufferCount();
            }
   }
   element.setTimeOut("GetBarcode", 100);
}
