RE: ISDN modems need 16650 serial ports.
Thanks for everyone's help. I did wonder about the Lava ($59 board). I'm going to settle on the Blue Heat from Connect Tech Inc, as I've been looking for a multi port card anyways. Now maybe I can actually hit that deadline of Friday! I'm now going to sign off the list. Thanks again for everyone's help!

I sent the URL in the belief they had German and English pages. Sorry, I should have checked before. :-| - To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to [EMAIL PROTECTED]
Re: ISDN modems need 16650 serial ports.
Hmm. Why exactly do you 'need' a 16650? If all you need are speeds above 115kbaud, or deeper buffers, you could theoretically go with an entire fleet for boards. The LAVA boards www.lavalink.com come to mind if you'd like something cheap and reliable. No offense, we'd all love a few cyclades Z-seris boards, but that's just not an option for some people. Read this article: http://www.lavalink.com/LIBRARY/Products/Lavaports/LPFAQS/FAQ_650_AND_ISDN.HTML For ISDN, what's happening is that some serial ports have very shallow buffers (usually the older 16550s) so everything's tranferred a byte at a time, hence the slowdown in apparent speed.

The Cyclades-Ze is an intelligent multiport card based on 16C654 (quad UART) chips (which basically are 4 16650 UARTs in one chip). More info about the board at: http://www.cyclades.com/z-series.html However, the minimum number of ports provided by a Cyclades-Ze card is 16 (up to 64 ports per host card). So, if you only need one or two serial ports, you may be better off looking for other solutions. Hope this helps.

Vision Systems (Norderstedt, Germany) have 16550 and 16750 boards, ISA and PCI, one of those may fit.
