LogFile in /ports access-server only logs one direction

RouterOS General

I have set a log file up in a remote-access server;
/port remote-access add port=serial0 tcp-port=10001 log-file=data.log

I am sending and receiving data thru the serial port from a telnet client on a host machine.
The log file only records data that is incomming to the serial port, even though I have duplex data.
Why wont the log file record data being sent out of the serial port?
How can I work around this?
