>Description:
	I was handed a modem card at work which appears to be of the
	"no-name" variety (the inscription says "V.90 56K FAX MODEM"),
	though the manufacturer/product should be discernible from the
	CIS debug info below.  This card fails to work on my IBM T21
	laptop.

	I've tested both with a pure pcmcia kernel (no cardbus devices
	configured), as well as a cardbus-enabled kernel, and the
	symptoms are the same: attempts at opening the serial device
	corresponding to the modem card appears to "almost" hang the
	system.  What this "almost" means is that I just barely
	managed to switch virtual consoles (using wscons), but typing
	anything (to login or the tip session with the modem card)
	fails to elicit any response (i.e. no echo).

	The failing pcmcia modem card (and the cardbus/pcmcia support)
	probes as:

	However, my old trusty 9.6/14.4 modem card *does* work,
	though, and it probes as:

>How-To-Repeat:
	See above; try to use a similar card on an IBM T21 laptop.

>Fix:
	Sorry, don't know -- hints for debugging appreciated.
