I need to change the IP address on a Bossanova e-twinax print server. Bossanova was no help unless you pay them for a support contract. You're supposed to be able to http into this, tried it with no response. Also tried hooking a com cable to the comport and a PC, says I'm connected but no response to keystrokes. This unit was working until we changes our network addressing. Any help or links are appreciated.
