Serial port left marked busy?

» close window

The Question is:

 
Hi,
 
4 Clustered AlphaServers 2100/A 4/275
 
We have a modem hanging off TTA0:
 
Every so often we get in a situation while using the modem where there is a
 communication problem and TTA0: thinks that it is still busy. We don't think
 that it's the config of the modem or the terminal settings as 99% it is fine.
 
The question is how can I reset TTA0: to become idle again when it's got itself
 into this busy state.
 
Example.
 
There was a problem with the transmission, nothing is using this port anymore
 however
 
show dev tta0:/full
 
Terminal TTA0:, device type unknown, is online, record-oriented device,
 carriage control, device is busy.

Reference count                0
Default buffer size                  80
 
The only way we have been able to clear it is to reboot the machine.
 
The workaround at the moment is to use a com port on one of the other Alphas
 and reboot the machine in an outage.
 
 
 

The Answer is :

 
  Please contact the Compaq Customer Support Center, as this would
  appear to be a rather unusual state within the terminal driver.
