I am running CGate on a relatively old PC (version 1.8.3 of toollkit). I am connecting to a CBUS network via the PAC and, first time round it all worked fine. Add New Hardware Wizard detected the COM port as COM3, installed the driver and I was able to connect. One reboot later it reinstalled on COM4 and since then I have been unable to connect. I should point out that COM1 and COM2 are disabled in the BIOS as I ran out of interrupts.. Any one any ideas? Thanks Mark
