I have two ME-3400EG-12CS-M switches.
I was working using the console, suddenly the console of one (only one) of the switch start showing garbage.
A telnet session to this switch works fine.
Im using putty. 8 bits, 9600, parity none, flowcontrol none.
I tried change the speed,flowcontrol, parity, etc, nothing works.
I did a telnet session and force 9600 in the line con 0 without success.
After execute via telnet a write erase in the switch, the garbage continues. Now Im unable to log in in to the switch because I erased all the config.
Its posible fix this issue?, may be using a keystroke in the console?

Can you try using a different application like TeraTerm or SecureCRT? TeraTerm is free

I did, also I tried in diferent pc, new console cable, etc., same thing.
Before I erase the nvram, I was able to log in via telnet into the switch. I checked the con 0 parameters, everything was with its defaults (9600,8,1,none,none).
I believe that it's possible switch the console port parameters with some keys combination like CTRL + something
