One thing I'm interested in is configuring things so that I can establish a 1 or 2 B channel connection on demand. My ISP supports Multilink PPP; therefore, I'd like to set things up so that if I know I'm going to be needing all the bandwidth I can get, I'll establish the connection using the two B channels. (It would be great if the Linux box could be set to timeout after a period of bandwidth "saturation", drop the single B channel connection, and then reconnect using both B channels....) The other problem I've got is in using an external ISDN TA and both B channels is that I'm going to have to have a high-end serial port that supports 230,400bps or more if possible.... Right now, the Linux box I'm using to connect to my ISP is only using a 16450 UART. I'll have to upgrade that, too. I wonder if I can drive a 16550 beyond 115,200.... > Ascend Communications > is rumored to be writing a NetBSD driver for their ISDN card, so > maybe they'll do one for Linux?! Wouldn't it be nice? And much easier on all of us... <grin> Maybe a little "pressure" (i.e. read "demand" from the Linux community) would entice them to do so.
