Nowadays, even desktop computers have few parallel ports. But for engineers, both parallel and serial ports are essential interfaces, especially serial ports. For computers without a serial port, a convenient solution is to use a USB-to-serial chip to virtualize a serial port. Many manufacturers produce such chips, such as CP210x series from silicon LABS, TUSB3410 from TI, CH34x series from Qinheng, and FT232 series, PL230x series, ARK3116, etc. From the perspective of stability, the FT232 series is still reliable, and you can use it to debug the program without worrying about the blue screen. The FT232R chip is a single-chip solution. Generally, peripherals are not required for general use. Even the crystal oscillator, USB matching resistor, and EEPROM for product information have been integrated inside. FT232R also has some more useful functions.
