Hi,
I am a beginner with LPC/ARM.

When I connect LPC Link2 via USB to my computer and launch Debug there appear 2 "HID Standard Devices" / "CMSIS-DAP" and "LPC-SIO Port", and also "Ports (COM and LPT)" / "LPC-LinkII UCom Port (COM3)". Maybe also some others I haven't noticed..

Do I understand right the HID interface is used for JTAG/SWD debugger and the port COM3 is free to use ?
I see on the schematic diagram of Link2 that "Serial Expansion Interface" connector J3 contains pins UART2_RXD + UART2_TXD;
when I open this COM3 with TeraTerm or other UART terminal and enter some text, will it be transmitted to this UART2_TXD ?

I know I could test it myself, problem is with the 50mils fine pitch headers, not so easy to connect anything here quickly.
My plan is to interconnect Link2 (UART2 pins mentioned above) with NGX LPC-4330-Xplorer / connector J8 / pins 9,10 == U0_TXD+U0_RXD.
Then I could test application with UART output without a need for additional TTL->UART->USB converter.

Any comments appreciated.
