I am using dialup I/O however if an abnormal disconnection occurs (e.g. phone line is unplugged or modem locks up) then it is possible that Citect’s dialup subsystem gets into a state where it will not be able to dial any devices. How can this be fixed?  

An issue has been identified in the dialup subsystem where an abnormal disconnection can cause units that are trying to connect to be continually reset to the pending state, preventing them from dialling up.

This problem has been resolved in v7.00.
