The USRobotics 56K* USB Soft Modem delivers the performance and reliability
USRobotics is known for in a compact, cost effective form factor. Broadly compatible
with Windows including 64 bit and server systems, the modem uses the CPU of the
host computer for high compression throughput due to direct parallel access. Features
include ring detection and qualification — eliminating unintended wake-on-ring events
due to activity on the phone line other than ringing, as well as handling pulse dial
control to eliminate system timing dependencies common with soft modems. The
USRobotics USB Soft Modem is fully compatible with V.92 and lower rates, making it
ideal for compact POS solutions that only require V.34.
