Ok.. check it out: 	http://www.cda1.com/isdn_prd.html

The CDA WWW page is out of date but I spoke to Kevin Murray 
at (703)821-1859 x121 [sales rep] and here's the facts:

	- The driver doesn't currently (3/18/97) support 
	  ML/PPP, only PPP (ie. 64k vs. 128k).  You CAN 
	  have both B-channels running data but they just 
	  won't MultiLink together.  A work around for 
	  this is for both B-channels to call into another 
	  ISDN-enabled Linux box and run EQU PPP load 
	  balancing across both WAN links.

	  The reason for this is that USR and CDA are
	  having a political fight over obtaining the 
	  necessary technical info to get 128K ML/PPP
	  connections running (TurboPPP issue I belive).  
	  They are hoping that this will be resolved 
	  in ~1 month.  But then again.. either 3Com 
	  will help or hinder this process.  

	  (see the bottom bullet for more info)


	- The current driver price is $59.95 for the 
	  Messiah object files to link into your 
	  kernel (source code will NEVER be available).

	- They support both the 2.0.x and 2.1.x Linux
	  kernels

	- You can e-mail in a request to get 30-day 
	  trial copy by e-mailing kmurray@cda1.com 
	  (sales rep) who will then forward the request 
	  to Steve Nichols (Product manager) for 
	  processing.


    ***  From the conversation I had with Kevin, it is
	  HIGHLY doubtful that a free GNU driver for the
	  USR Sposter128 will EVER come out.  According to
	  Kevin, the Sportster128 is a "dumb" card that 
	  needs all of the various ISDN (q.931, etc) code
	  uploaded into it EVERY TIME the power is cycled.
	  CDA evidently had to write all of this ISDN code
	  in addition to the Linux card driver to get this 
	  all running.  If this was just a driver issue, then
	  you would soon find a GNU driver.. but this isn't
	  the case and I doubt someone would goto these
	  great lengths to only give away the code!
