I installed gl-uart_3.0.11-1_mips_24kc.ipk manually into ROOter OpenWRT with opkg.

When I run:

gl_uart 474c190107 or gl_uart 474c1a0138

I get the response:

Fail
Killed

Is there something else missing that I need to add?

According to GitHub - gl-inet/gl-x1200-uart sending those commands would cause the signal LEDs to be full.

Thanks!
