Hi,
My rb435g has stopped respond on key pressing in serial console session.
I am using null-modem cable and "baud-rate=115200 data-bits=8 parity=none stop-bits=1 flow-control=none" port settings on RB and PC sides.
Serial connection was working normally for ~1year using described settings. Currently I am seeing only output from router during boot/shut-down, but can't type anything even in RouterBOOT menu or than in login prompt
I have tried connecting from two different PC using different null modem cables via minicom/putty/gnu-screen, no luck so far
Netinstall with default settings to RouterOS 6.15 and RouterBOOT update to 3.10 isn't resolve my issue .
Are there any solutions left, or RS232 hw driver/controller is broken?
Any advices/help appreciated.
TIA
