I was looking around and seen zoom has 2 external conexant chipset modems the 3048 and the 3049. I looked around and got the manual for both and I cant see what the difference is. What is the difference? And they had the same modems in agere chipset to. Looks like they stopped making the 304x agere modems, are the 304x agere modems any good anymore? Is agere as good as conexant? Seems like everyone is starting to use conexant instead of agere now. Dont know why but stores that use to have the zoom modems dont have them anymore.

Zoom hasn't used Agere chipsets for several years now, and does not support the product that it previously manufactured - personally, I wouldn't buy anything with the Zoom name on it because of their past lies & lack of support for their own product.

The difference between 3048 and 3049: 3048 comes with Mac comm software.
Zoom has manufactuered MANY versions of the 3048/3049 - the L and C, and even with the C(onnexant) chipset, there are different versions of the ACF chipset in different 3048/3049 modems. Again, support for anything but the current version will be almost nill; and support for the current version is likely to disappear the next time they make a manufacturing change.
In the case of a h/w controller modem like the 3048/3049, support involves making firmware updates available.

Aloha! Richard.

I would avoid external serial modems in general.
Performance and stability are affected by the motherboard serial port (UART) speed limit.
http://www.hardwarecentral.com/hardwarecentral/tutorials/57/1/
This article recommends to upgrade to a serial card using a newer UART and higher clock frequency.
The cost of a serial card in addition to the modem is a high price to pay for a stable connection.

If you already own a external serial modem you can bypass the UART speed limit by using Stac Compression.

Microsoft owns Stac so this only works in Windows. Not BSD or Linux.
