IP CCTV Keyboard Controller Linux Image

[SaadMasood 0]

I am controlling my CCTV system from C100 Keyboard, see the picture in attachment. I forgot the password and was unable to access from web. I thought to give it a factory reset then. Unfortunately I could not find any reset button and I tried accessing it from console RS232. Set baud to 38400 and accessed. I searched over net and found that I should set environment varirable like below from UBOOT.

=> setenv stconfigignore true
=> saveenv
=> reset

I did the same but my keyboard got stuck.
