Re: [SLUG] more RS232: USB-RS232, PCI ?
With this Verbatim card (good price!) you only get one external port and on-card headers for the other 3. You'll need to add the cost of 3 backplane adapters, or scrounge some from 286 / 386 / 486 class machines that usually had them. Beware though - there are two seemingly equally common ways of wiring the serial lines on the header, either: 1 2 3 4 5 6 7 8 9 - or 1 3 5 7 9 2 4 6 8 - If you find yourself with the wrong sort you can lift the IDC cable off the header female and re-lay the wires in the right sequence. Most multi-port serial cards have an octopus cable - I guess the meaning is good even if the count isn't right! You can also get 4-port cards with modular RJ45 connectors, which is nice and neat - if you can handle the cabling. They don't implement Ring Indicator (pin 9) but I guess you are only after a 3 or even 2 wire connection. You should be able to see all ports in Linux - there used to be specific drivers for DOS, needed because it had very crude IRQ handling on it's serial ports. hth, Kevin.

The specs do mention linux ;-) http://www.verbatim.com.au/products.cfm?productID=KWL221N2 and http://www.verbatim.com.au/technotes/Linux_S.txt There is a another bunch and I have a couple of their cards. www.sunix.com.tw you can buy them at (e.g.) www.lmc.com.au You just need to make sure that they are either 16c650 chips or compatible, which means the OS just finds them. Note: linux kernel provides for only FOUR serial ports, so if you have the MB with two ports you can only use 2 additional ports however, there is a 2 port and 4 port version.

Re: 6 comm ports ?: [SLUG] more RS232: USB-RS232, PCI ?
It depends on which card you're using. If you're using a card that exports lots of 8250/16450/16550 chips then sure, the default serial driver only tries to probe 4. Lots of multiport serial cards have their own driver, do their own thing and aren't supported by the PC serial driver; they have different restrictions.

Watch out if you need to do something other than RS-232 serial data over them: the control and reporting of the additional control lines varies, and on some USB to serial devices are specially wired for serial modems.
