You sure it's not your laptop/PC/cable that is set up wrong, as it seems strange that 3 of your devices are faulty? Can you console into any device with your PC? Your COM port settings should be 9600, 8, N, 1, N.
yes, three routers console port r faulty and i am having 6 more routers working fine used setting 9600,8n1 none, i m sure console ports r faulty does anybody knows the uart used for console port for diffrent series of routers so that i can repair.
CONSOLE Port problems.You can connect to the Routers 1600,1700 and 2500 using Telnet connectivity.Just remove the Console Cables from the Routers.Launch telnet from the PC(If Windows, Click Start->Run and type Telnet) Type the IP Address of the Router(say 2500),should be the IP for Fastethernet port ; enter the console username and the password for the Router.If TELNET username and password for the Routers are already enabled, try connecting using the Telnet username and password.You can also use the AUXILARY port to connect to the routers(only for Remote connectivity).Good Luck.
