UltraPort

technology
UltraPort technology can double the throughput of Diva Mobile. When the
computer-to-modem (DTE) speed is set to 115,200 bps in your communications program,
UltraPort automatically transmits at up to 230,400 bps with average 8:1 compression
(using LAPM and V.42bis). However, overall throughput is limited by phone-line quality
and the performance capabilities of the remote modem.
Note: Your computer might not be fast enough to handle the incoming data. This is
probably the case if you are disconnected often, or if you see many file transmission errors
(excessive errors can abort a file transfer). If this occurs, see Troubleshooting
on page 49.
