how to open telnet and console into a 3com switch

I am trying to open up telnetting on our 3com 2948 switches.  I know i have to console in, but how do I console into these switches.  I tried a console cable hooked toa db9 to usb connector using teraterm but nothing comes up.  What am I doing wrong?  Or should I use a crossover cable?  Also how do I open up the telnet port on the switches?

ok cool :)

like i said all switchs have different baud rate (on cisco you can cange them to what you want) and unless you have it matched both end it wont work) 9600 is the most common speed you find on switchs and router. It seem you have one that is slightly different.

Glad you got it going mate.

Switches / Hubs

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
