I was wondering if it is possible to use a USB to RS-232 (RJ-45) cable for remote serial access. Specifically, I’d like to know if I can connect such a cable and use it to establish a remote serial connection, as shown in the image below:
are you looking at deploying the Mango, and having the USB to Serial cable to connect to other devices, I've got both items, what do you want me to test?
USB-to-TTL chipsets like CH340 are commonly used in Linux/ARM, but I'm not sure for USB-to-RS232 chipsets. I've heard that some don't support Linux at all.
If you really want to use it, using MAX232 or so with Mango's TTL pin or USB-to-TTL adapters may possible, I guess.
Does a driver exist for the device in stock kernel?
Does the driver exist for this architecture??
I assume that any driver that exists could be loaded.
That's a Cisco console cable in the image.
Usb to management ethernet.
I have Ubiquiti security gateway and Edgerouter Lite running OpenWrt I can connect to via serial using one.
I conducted some initial tests, and everything appears to be working as expected. I will attempt to console into a device later to confirm functionality, but here are the steps I followed:
1. Installing USB to Serial Drivers
First, I installed the necessary USB to Serial drivers by running:
