It's not the processor on a 286 but its UART chip which can't handle a fast modem's data speed. They usually contain an 8250. Internal modems carry their own UART which should be alright.

I recently got a Sportster 28.8 with 33.6 Kps data, and I can upgrade my modem for $7 US and get a new EPROM chip to plug into the unit. I think you had to buy the modem between November 25, 1996 and January 4th 1997 to be eligable. My model number is 839 and my modem seems to have the "hang" in it when I call BBS's, how do I get rid of it it? Is there a fix or setting change I can do?? I guess if I upgrade the chip to 56.6 it will go bye bye? I think all new modems they are selling now are 56.6k modems, and I think you can download the software to upgrade them at the usr robotics web site at www.usr.com Thanks for your help!

I can't tell you per say about the Accura but, it has had some nice reviews. I have the Hayes Optima 33.6 on one machine here, and it has not given me an ounce of trouble. The one thing you might want to think about however, is do you have someone in your area supporting 56Kflex? If not do you have someone supporting X2? If neither, than I would not buy one. BBS's I suspect will not have one attached to it any time too soon as they do require a digital line which means more expense to the sysop. I had a Motorola Kflex for a short time. Nice. But, I don't believe there was any difference between the X2 and Kflex. And if there was I certainly never saw it.
