RB112 Serial Console Problem

Hardware MikroTik hardware general
1

The seemingly simple goal is to connect to a RB112 2.9.40 via the serial port.

I lost ethernet communication with it during initial config. Only the blue LED is lit. So, I thought I would try a net install.

115200bit/s, 8 data bits, 1 stop bit, no parity, hardware flow control.

From the Serial Console I can watch the RB boot up and ask for a log in, but it does not appear to be receiving my keyboard input.

Searching for the cause I have tried:

  • 4 different DB9 to DB9 Nulll Modem Cables - same result.
  • Tried to access serial port on two other good working RouterBoards - same result.
  • Tried using HyperTerminal serial connection on two different notebook computers - same result

I have searched through various other “serial console” postings without finding an answer…

I must be making some dumb MT newbie mistake here… what is it?

Use “none” for flow control. You should be able to use MAC telnet or WinBox via MAC via the ethernet port.

Winbox would not talk to it (period).

setting the flow control DID fix my serial communication problem - THANK YOU!

And, I will go in and correct the WIKI so that the next poor fool does not trip over some incorrect information :- )
