There is a netport branch, but I don't know enough about the Personal Solution Pac software to say whether that branch could be merged into PSP.

Handoko: Do you know how the serial-over-IP adapter handles baud rates?

The PSP software start a warning that  power is down in every 1 minute. Now, I switch the connection of the UPS right away from PC to the serial over IP device ( that already standby).  Switch the PSP to use the virtual port.... now somehow, the PSP will still warning me about the power down for another 2 warning... then it stop...
