Important
It is important to note the following because of the internal features of the MS
Windows driver for serial interfaces:
• When data entry is completed, the MS Windows RTS signal is not set to
LOW but remains in the HIGH state thus signalling to the sender that it is
ready to receive.
Therefore always start the receiver and then the sender.
• When data output is completed, i.e. when ETX has been sent, a few more
idle characters are sent. These characters might also be stored by the
receiver (PCIN with setting: binary format).
