I have brand-new RB1100AHX4. I have used it for 2 days. It works great, and I was able to update the firmware via Netinstall. Current firmware version: 6.43.7.
The main problem is that I absolutely can not connect to the serial port.
Here are all the cables I used.
In my dmesg I see: Product: FT232R USB UART or FT231X USB UART. Also, I tried one USB-Serial Controller by Prolific Technology.
As for the software, I have used minicom and screen on last Debian/Fedora 29, and Putty on Win7. I 've used only recommended settings, i.e.:
In all cases I see the same thing, namely the empty screen in Putty/Minicom/Screen. I also tried to reboot the router and watch what was happening on the screen. But nothing happened. Obviously, this is abnormal behavior.
Code: Select all
baud-rate=115200 data-bits=8 parity=none stop-bits=1 flow-control=none
In the case of one of the blue cables, I was able to enter some garbage characters (but did not see the normal command prompt). And later, after logging in with winbox, I saw warnings about login errors with incorrect characters.
1.) Should my cables work? Can you suggest a specific cable model (and where can I get it) that will work exactly? (I wouldn't want to go through a lot of cables hoping to buy the right one).
2.) Is it definitely a breakdown and can I contact the seller for a refund?
3.) I can list ports using:
/port print detail
/system console print
And I can access it using:
Are these facts evidence of serial port health and the absence of a breakdown?
