Hi I use traditional Direct Console cable to connect from HP Switch to PC. I changed the settings for Putty as well.
This is what documentation says:
Connect a serial console session with the switch, using the black console cable that would have shipped in the box of any ProCurve switch. The part number of that cable is 5184-1894. The part number is stamped directly on the connectors.
Use a VT100-compliant terminal emulator such as Hyper Terminal or Tera Term Pro to make the serial connection with the switch. Use the following COM port settings to create a terminal session with the Switch 4000m: Any baud rate from 2400 to 115200 (the switch automatically senses the speed). * 8 data bits, 1 stop bit, no parity, XON/XOFF flow control. * For Windows Terminal program, also disable (uncheck) the “Use Function, Arrow, and Ctrl Keys for Windows” option.
I don't know where is disable (uncheck) the “Use Function, Arrow, and Ctrl Keys for Windows” option is?
