Zoom Telephonics is now shipping a USB version of its V.90 external modem, the Zoom/Fax Modem 56K USB.

Being USB-based gives the product certain advantages: it requires no power and is speedy – it can handle data speeds of up to 12Mbps, though bandwidth and modem limitations constrain maximum efficiency.

The £59.50 modem transmits at uncompressed speeds of up to 33.6Kbps, receives at 56Kbps (uncompressed) or 230.4Kbps (compressed).

Features include: Flash memory – for modem script upgrades – fax software, and ZoomGuard. ZoomGuard is claimed to be a "superior" lightning protector -lightning is a major source of modem failure.
