Hello all,
I am farily new to the RouterOS and I need some help.
I am trying to get the serial port to act as a serial device server.
As I have it setup now when i type “telnet 192.168.88.1 50000” (yes I changed the telnet port number) I get the console login prompt, then I have to type “system serial-terminal”, “serial0” and “ctrl A” to be able to pass data over the port.
I want to be able to type “telnet 192.168.88.1 50000” and be connected into the port as serial terminal directly, no typing of anything.
How do I go about doing that? 
Thanks
Remote-access feature is used for it, specify Telnet port that will be redirected to serial-port directly.
/port remote-access>
allowed-addresses copy-from local-address port tcp-port

Hello sergejs,
I have tried what you said and it works, but I dont see any data being sent across the port. I thought it was because of old firmware, but after upgrading to OS5.6 I still have the same problem. I have opened a telnet session and hyper terminal on the same PC. Typing from hyperterminal does not show anything on the telnet screen and vice versa.
How do I go about troubleshooting?
What do you think is blocking data?
If you telnet to specific port and type command in. Is there any output?
Nope I don’t get any output whatsoever.
What also happens is that the telnet/tcp session keeps disconnecting a few seconds after I connect. Rarely does it stay connected.
But /system serial-terminal serial0 works solid?
