"It's getting very hard to find real PCI slots > any more." :( Well digi (www.digi.com) makes some nice PCI serial cards, that work with the jsm driver. Not sure how many models are supported, but certainly I have used the 2 port card with DE-9 connectors. A little bit of patching will make the jsm driver run any exar 17[CD]15[248] based card, like the ones we use on the routers I work on. The digi cards use a rebranded exar chip with a different PCI id. Much better than using the 8250 driver to run the exar's in PCI 16550A mode, although it does work. They have PCIe cards too although I have no idea if they use the same interface or not (it would make sense to do so on the part of exar though). > It seems like some companies (notably *cough* Intel) are > on a little jihad to get rid of serial ports... > > I'd think that in a controlled environment (fixed set of > USB connections) USB should be able to meet fairly chosen > "real time" latency ceilings.
