  • 1.Get a serial console cable. Note that I went through several of them before I found one that would let me SEND characters to the device; I could see the switches boot activity but nothing I typed would appear on the console window… so if you have this problem, get another cable!
  • 3.Start your HyperTerminal using the following settings:
    connect using COM1 (or whatever port you are using)
    19 200 bits/sec
    8 data bits
    No parity
    1 stop bit
    No flow control
  • 4.Power up your 4200G (or similar aged 3Com switch)
  • 5.In the Hyperterminal Window you will see something like, and you will have just a second or two press CONTROL+B to endter the book menu:
    Starting……
