Re: ISDN modems need 16650 serial ports.

[Mike Hudson]

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.   Hope this helps,   Mike Hudson ----- Original Message ----- From: Andy Kennedy To: [EMAIL PROTECTED] Sent: Tuesday, April 11, 2000 1:38 PM Subject: ISDN modems need 16650 serial ports. Because of this, I need one.  Does anyone know a good serial card that supports 16650 and is still being made?     Andy
