Modem Compatibility
The SLTA-10 Adapter has been tested with the following modems:
Best Data
Smart One external modem 33,600 bps Data/Fax modem
Diamond
SupraExpress 336e external faxmodem
Hayes
Accura 336 external fax modem
US Robotics
Sportster Voice external 28.8 faxmodem
Synchronous communication should be disabled when synchronous modems are
connected at lower serial bit rates (less than 4800 bps). Alternatively, data
compression can be disabled at lower bit rates. For example, two V.42 or V.32bis
modems connected at 2400 bps will have very low throughput due to the slow serial
bit rate.
You should disable XON/XOFF flow control in the modem when using it
with the SLTA-10 Adapter.
Note: When using the Hayes Accura external Fax Modem with Simultaneous Voice
and Data 33.6 modem with the US Robotics 28.8 Faxmodem with Personal Voice
Mail, an incompatibility in communication occurs. Testing the two modems via
Hyperterminal reveals that the CD signal (Carrier Detect) is incorrect. Due to this
communication incompatibility, do not use these two modems together with the
SLTA-10 adapter.
