COM-port, or RS232) is slowly disappearing from desktop and laptop computers, but it's still a very important tool for embedded engineers and people controlling equipment in general.īack in the Virtual COM Port application, click on “Add” in the Virtual Serial Port dialog box, which will bring up the “Edit Connection” window.

You can use the regedit tool to reach this key and make sure the serial ports defined on your machine are there (including the virtual ports created with com0com or another emulator).

This chip has a UART port which means we can connect it directly to a USB-to-serial converter (such as the FTDI 232R). ![]() To test our Python serial port program, we will be using a very tiny PIC chip, the PIC16F1825, which will be coded using XC8.
