How to disable <BackSpace> on Solaris ?

[sbk]

Hi All,

Does anybody know how to disable the <BackSpace> key while entering characters at the unix prompt in Solaris? I have a password prompt and while the user enters his password, I want to disable the <BackSpace> key, such that if the user hits <BackSpace> before he/she finishes typing then it should beep a sound and should not work the way it should work.

I need this info very urgently, any sort of help is greatly appreciated.

Thanks,
sbk
