Modify BAUD speed on Cisco Switch and Router

I have a rack of switches and routers that I connect through from a terminal server. I noticed how slow and laggy the switches and routers would be after entering a command. The current baud speed is set at 9600. I wanted to change this to 115200.

Router> ena
Router# conf t
Router(config)# config-register 0x3922
Router(config)# end
Router# reload
Put "n"  you dont need to save configuration

Immediatly press CRTL + Break keys

It should put you in Rommon mode
rommon 1 > confreg 0x3922
rommon 1 > reset
Router or switch should reboot, thats it.
