Haxxio UDP Serial Port Redirector
If there is no application connected to the port, it will be captioned as "Closed".
Once an application connects, the field will reflect the settings of the port as set by your connecting application. The field will then display something like "Open 4800,N,8,1" reflecting the state of the port.
The string displayed is built up as the connecting application calls for settings of the serial port, so there may be either an incomplete string, or just the word "Open" if the connecting application hasn't got around to setting the port parameters yet. The setting of the serial parameters normally happens so quickly that the field changes from "Closed" to "Open 2400,N,8,1" apparently instantly.
