Pardon my ignorance.

typing dmesg in Ubuntu, I get the following messages:

Product: Olimex OpenOCD JTAG ARM-USB-OCD-H
[ 9062.541146] usb 1-2: SerialNumber: OL87B474
[ 9062.552768] ftdi_sio 1-2:1.1: FTDI USB Serial Device converter detected
[ 9062.552798] usb 1-2: Detected FT2232H
[ 9062.552992] usb 1-2: FTDI USB Serial Device converter now attached to ttyUSB1

Correct me if I am wrong, with the physical RS-232 port to which one end of the serial cable connect to, and the other end of the cable connects to the target board, is it correct?

Appreciate your comments.

The RS232 connector of ARM-JTAG-OCD-H serves a USB-RS232 converter. For example, if your computer has no RS232 port, you can use the one on ARM-JTAG-OCD-H. It has nothing to do with the JTAG debugging or programming, it is a separate thing. The levels are +/- 6V.

The programming interface is the JTAG connector that gets connected to the target.
