Hello, I have forgetten my password for my test cisco 2950 switch.  I am trying to get the switch into rommon mode so that I can carry out the steps to reset the password.   When I reload the switch and press the crtl break the switch doesnt go into rommon mode and gives the following output -


C2950 Boot Loader (CALHOUN-HBOOT-M) Version 12.0(5.3)WC(1), MAINTENANCE INTERIM

WS-C2950-24 starting...
Base ethernet MAC Address: 00:07:50:c0:1d:40
Xmodem file system is available.

The system has been interrupted prior to initializing the
flash filesystem.  The following commands will initialize
the flash filesystem, and finish loading the operating
system software:

    flash_init
    load_helper
    boot

switch:

Any Ideas anyone ?

no-no this is a normal startup, you have to interrupt boot process with ctrl+brake
I would suggest using putty or secure crt, because they can pass ctrl+brake sequence to the switch.
