DataMiner supports serial communication, allowing protocols to define one or more connections of type "serial". DataMiner runs a process called "SLPort" which takes care of all communication to and from devices connected to either a serial port or an IP port.

So we support both a direct serial cable, if the server itself has those connectors, or through another device that does serial to ip conversion such as a Moxa device.

For more information I would refer you to the DataMiner Development Library that defines how such a protocol can be written using connections of type Serial.
