How to enable VCOM functionality of J-Link or J-Link-OB models that support it, is handled in this wiki article.Always test before buying! Because of the way VSPE emulation works, please ALWAYS test VSPE (without activating it) on your target operating system before purchasing it - to see if it suits your needs (which is 2 pin in most cases, such as SWD), and also delivering performance of up to 3MB/sec. Some people also consider the speed a limitation.ДЄ better alternative in many cases is RTT, where J-Link communicates with the application via the debug interface, not needing pins in addition to the debug interface itself If hardware flow control is used, then even more pins (typically 4) are required. Typically in addition to the pins used for the debug interface. The main disadvantage when using this to communicate with the target processor is that 2 pins on the target processor are lost (Rx and Tx) for this purpose, Having the bulk of data transmitted in a continuous UART transmission is better. So, the more fragmented the data is received by J-Link, the more USB transactions need to be triggered (with very few payload bytes in them) which brings down the max.

This is because the data needs to be forwarded via USB to the host PC and for USB there is latency between USB transactions. However, what the actual throughput is, also depends on if the data is received continuously. These lines exist on both ends (sender + receiver) and are crossed for connection, so:

RTS, driven to indicate to the other side if driving side is ready to receive more data.

CTS, sampled to check if the other side is ready to receive more data.

The following pins are defined for hardware flow control: Hardware flow control is designed to make sure the receiver (on both ends) does not get data faster than it can process the data, to stop the flow of data before bytes are lost due to buffer overflow. On some J-Link OB models, hardware flow control is enabled, but optional. In many cases, the communication port is simply used for terminal I/O, allowing theДevice to communicate with the user (typically the application programmer).Д«ut we have seen cases where it has been used for entirely different purposes, such as system setup, firmware updates. There are many different use cases, as any kind of communication can be done via a virtual COM port. to get terminal data from the target deviceДЄnd one exposing the J-Link USB interface that is used by IDEs etc. One interface exposing the VCOM port that may be used by any terminal application etc. So a J-Link in this case is a multi-interface USB device. The Tx and Rx pins of the target UART are connected to the J-Link or J-Link OB which will forward this data via the VCOM functionality over USB to the PC the J-Link is connected to. The SEGGER J-Link as well as most J-Link OBs support VCOM as an additional feature to avoid the need to expose an additional COM port or additional USB connector on the target board. Identifying Virtual COM Ports on a windows machineДevice Manager before VCOM device has been connected:Дevice Manager after VCOM device has been connected: Once the adapter has been connected to the PC, a new COM port will show up which can then be used as a normal COM port by terminal applications etc. These USB to COM adapters that have a USB connector on one side and a COM connector on the other one allow retrofitting a modern machine with a COM port. The typical replacement is a a USB device to show up as a COM port at the PC. Most modern PCs and notebooks no longer provide COM connectors on their mainboards due to the large size factor of the COM port connector and the fact that very few consumer users have any use for them.
