Miles Mann: '......If a crew member logs into the PMS from the serial port via a LapTop computer, the radio port will get a BUSY message until the Serial port computer logs off.....'

The Personal Message System on ISS (PMS) has a built in Time-out timer for stations on earth that log into the PMS.

If a connected Earth Station does not send any packets for approximately 60 seconds, the PMS will start a disconnect process and will eventually disconnect the Earth station to free up the radio port for the next user.

Unfortunately this time-out feature is not implemented for the Serial port on the TNC.

If a crew member logs into the PMS from the serial port via a LapTop computer, the radio port will get a BUSY message until the Serial port computer logs off.

The PMS on ISS has been issuing BUSY messages to all log in attempts since October 27 aprox 20:00 utc.

We will have to wait until the crew checks the PMS again later this week.
