Using the Interface Module with a Portable Computer
Some portable computers have power-saving modes that power down the serial
ports during inactive periods, occurring most often when batteries power the PC.
The serial-port power-saving feature causes the RS-232 interface module to go
offline and to cease communication with DeviceNet Manager. You should
disable the serial-port power-saving feature to use the RS-232 interface module
with DeviceNet Manager.
If you experience a problem with the RS-232 interface module going offline
unexpectedly, use the setup program of your portable computer to disable the
serial-port power-saving feature.
