The target here is to directly connect a serial Graphic LCD on a USB port of the computer using a FTDI chip based USB adaptation module

The USB to UART Com option is already working while the RS485, I2C and SPI Serial Interface adapations are currently under development ( begin of 2017 )

In the same Window as the Text editor and the Hex Editor , there’s also a Serial Communication Tab and Panel. In the local Menu ( red arrow ) you can connect (open) the selected Serial Port.

You can choose the Transmit Only or the Transmit and Receive mode. Remember that the Transmit and Receive mode scans the serial interface for received chars, this loop is computing time consuming. You can close the serial port to stop this loop when not needed.

You can write data to send in the upper field and start the communication by transmit , and see the received chars in the lower field. You can also transmit the content of the Text editor.
