This library, then DLL, designed for use with weighing terminal CI-5010A on the RS-422/485 or RS-232 via a physical or virtual COM port over USB in OS NT/2000/2003/XP/Vista/7/8 and reads and decodes the data of the operation, gross weight, net weight, unit number, value and sign weight, units and features indicators. Restoring communications using virtual serial port automatically. ORDER use and limitations: 1. You can optionally set the COM port in the procedure 'reinit()' with constantly raised the flag of activation in the library is being processed. 2. Parameter gl_count procedure 'getdata' indicates the number of received packets of COM-port. 3. Implemented AutoTrack pulling converter RS-485/USB (via SetupAPI) and reconnect to the specified port initialization.
