More than that, you can change the type of data being sent immediately without closing the session. The same way during one session enabled, you can modify serial port settings, such as stopbits, flow control, parity control, data bits, highlighting, etc. whatever you need to follow the work of serial port. Serial Port lets you choose monitoring filters, thus saving your time and letting you track down only those specific events you are interested in.
