    ok, I stand corrected, but I'll bet you that most people don't have that many

    Hey, can you elaborate on all of that stuff, specifically what you're using and what software? Do you have a site with all of that stuff? What are you using the relay for? How does the alarm thingy work? What ODBII module are you using and what software?

    Thanks!

    I'm still working on my system. I dont have a site up yet since im not a HTMList. Let's put it this way, if Darmie's system makes you wet, mine's gonna make you jizz all over. BTW, a lot of cool gadgets require serial ports. PDAs, Cell phones, SONY joystick hack, my Panasonic DV Cam, bar code scanner just to name a few. Some people might not go as far as putting a bar code scanner on their car PC but hey the option is there. You never know. In the future you need wanna ring someone for gas for a ride or something.

    Also, that's assuming that you need 4 extra ports. If you already have 2 on your PC, do you really need a total of 6? Or even if you have done, maybe if you did need a whole extra 4 ports then you can do that route, however if you only need 1 or 2 more, then the hub + individual ones is definitely much much cheaper.

    Aside from the probs about the driver/OS not allowing more than one individual adaptor.

    My Plan is. Universal Remote with Serial Ira. There is one gone.
    Winamp button Control (probably the front from an old car stereo) there is another one.
    Serial LCD there is another one.
    Evenually touch screen for a TFT and there is number 4. Now if you are building using an Epia or a Laptop, quite often you only get 1 if any serial ports, so USB might be the only way forward.

    Having a spare to maybe be used to control externals such as car alarms or other things might be usefull too.

    I think a 4way Serial hub would be easier to hide as a block (on a flat plan bare boards(everything removed from it's original casing) case), but more of a problem to custom fit into a very sculpted setup (everything built behind the dash).

    To go back to the original topic, you should be fine adding an ISA serial card to your computer. In fact, on most modern motherboards the onboard COM ports are on an internal ISA bus anyways.
