login getty at serial console problem...
 

I am trying to make serial console(hyperterminal) password protected....but there are certain problems which i can't get rid off...here i am using embedded linux(uClinux blackfin processor)...i tried editing inittab getty by adding

console::respawn:/sbin/getty -L console 115200 vt100

which results in login prompt at console....

but the problem is it enters to root before login prompt appears...and also when password is typed an extra r is coming infront of password...

plzzz help me to find a solution for this.
