[WriteLog] DX Packet Cluster TNC Problem

[Mike]

Hello,

This problem has nothing to do with Writelog other than the symptom is seen
on the Packet Terminal screen.  The problem has to do with the TNC, PK-12,
connected to the computer running Writelog.  Presently getting a string
weird characters when the PK-12 is started.  This came on strange as it
seemed to be a gradual problem that started a week ago.  

Initially would see several lines of the weird characters that would
correspond to the " AEA PK-12 Packet Controller AX.25 Level......." then
the cmd: prompt would be seen.  The connect command could be entered and
connection with the local cluster node was made.  Spots were received and
could be sent.

This happened for several days until last Wednesday got a couple lines of
weird characters and no cmd: prompt.  The second line stopped and the TNC
didn't response to the keyboard (echo off).  Also, all the monitor LEDs are
lighted except for the xmit LED.  This is now the situation everytime the
TNC is started.

The connection cable has been checked and another working serial port on
the computer was tried with no success.  The memory battery was measured at
3.1 Volts.  

Any ideas on what could be wrong with the PK-12 or whatever is the problem?
