Answer

Error 922 can happen if you try closing a socket that was already closed by the server.
Error 923 can happen if trying to send data on a socket that is already closed.

These are very common and expected errors than can happened during normal functioning. Our out of the box software are designed to properly clean up and ignore them.

Customers can use following command to increase the log level of the HL7800 driver at runtime to get more info:

 attr set 201 3   <- HL7800 info log level attr set 201 4  <- HL7800 debug log level
