	I have tried the external modems e.g. 3com, Motorola 
	and they all worked fine. But I do like to use an
	internal card (because I hate those bulky AC adaptors).

	However, Motorola also makes an ISA
	card which is the internal card version of the Bitsurfer. 
	Have anyone had any experience with this card ? If this 
	card uses the similiar AT commands like the external one,
	we should be able to modify the modem interface sequences
	to make it look like a serial port/analog modem . 

	US Robotics also makes
	an ISDN ISA card (a little more pricy $389), it claims that
	it supports packet driver. Does anyone ever written a 
	FreeBSD device driver emulating a Packet Driver ?  

	Or any ISA ISDN cards that support CAPI which is used by
	the current ISDN driver. The German ISDN cards all support
	CAPI which is developed in Germany. However, I have a hard
	time in ordering  one here in US.

	In US, we use NT-1 and NT-1 is an U-Interface.
	In Europe, there are using S/T interface.
	NT-1 type of modem most likely will not work in Europe. 
	(Correct me if am wrong, thanks)
