OK, the Zoomer documentation states that PCMCIA cards are limited to =
50mA maximum current draw.
My specs for the Megahertz XJ1144 state its power consumption in =
operating mode is 725 mW.
So, how do mW and mA relate? I've long since forgotten the formula to =
use for this sort of calculation. Anyone else know? Can the Zoomer =
supply this much power?

While this isn't a bad trouble shooting idea, in this case it probably=20
wasn't the right one. What you may have done was turn one problem into=20
two: 1, getting the modem to respond; 2, getting the new drivers copied. =

For the moment, lets ignore problem 2, since I think the issue isn't the =
driver, but the modem itself.
In this case, I think you can trust what your Zoomer is telling you -=20
somtimes it does know best.
Here I refer you to your ever-trusty Zoomer owners manual. Make sure =
the=20
specifications for your new modem match the requirements listed in the=20
manual for the Zoomer. Most of the newer PCMCIA modems (not to mention=20
many of the older ones) need more power than the Zoomer can provide. =20
Remember these new PCMCIA cards were designed for laptops, which have a=20
lot more power to offer than the Zoomer could ever supply. I'd give you =
the page number and specification, but I don't have my manual with me at =
the moment. I could get for you if you don't have an Owner's manual.
I remember this is a problem I had when I was looking for a modem, but I =
should warn you that when compared to many of the rest of you out there, =
I'm a real novice.
Also, is there software that lets a Zoomer transmit at 14.4 ?
