M1ABD STOPPED WORKING.
When I got up this morning, I noticed that there were not many stations on the APRS map. It seems that all the stations left on the map had last been heard 40 minutes ago. When I checked back later, the map was empty apart from 2E1EJC and G4RS. M1ABD failed to respond to a Ping.
So, a trip up the hill was called for. Once again the top of the hill was alive with SEB men cutting down trees and working on poles.
When I got into the site I found that the power was on, the computer had re-started but there was a message on the screen saying that COM 1 could not be opened as it was already in use. This was obviously the cause of the problem as the TNC is connected to COM 1.
The problem appears to be with STARTUP.exe. Mr Google says that STARTUP.exe should be started with a /r switch, i.e. C:\Windows\System32\STARTUP.exe /r
But it appears the switch should be -r or the COM port is not re-started if the power is cut off.
I did several tests to make sure the computer would re-boot if the power was cut off and then restored.
M1ABD is back in working order again and the map is full of stations.
