6. Known issues
---------------
6.1 The USB Communicator V.90 requires the Windows 2000 to have minimum 64 MB memory.
The Windows 2000 may crash if the system has less than 64 MB RAM.
6.2 When some systems get into "sleep mode" and an incoming call is received by the
modem, the modem answers but the screen stays blank. This behavior is dependent
on the System BIOS and not on the modem. Some BIOS vendors choose to let the
modem answer, but leave the screen blank.
------------------
7. Troubleshooting
------------------
If your modem does not work as expected:
7.1 If ERROR, NO DIALTONE or a similar message is received:
(a) Check whether USB Communicator V.90 is connected to the analog telephone line.
(b) Use a telephone handset to make sure that the line is active and that there
is a dial tone.
(c) Check to see if the line is a PBX or a direct analog phone line. The modem
would not work with the digital lines.
(d) If the PBX analog line is used, you may need to dial 9, before the actual
desired telephone number (i.e. ATDT9,123-4567).
If the modem still cannot detect the dialtone when 9 is added, try typing
ATX3 before dialing.
NOTE that PBX lines typically can only support V.34
rates (33,600 bps, 28,800 bps, ...) and NOT V.90
rates (49,333 bps, 50,666 bps, ...).
7.2 If dialer application (i.e. Hyperterminal) does not detect modem:
(a) Check whether HyperTerminal is configured to the right port.
You can find the USB Communicator V.90 COM port number in
Control Panel/Modems/Properties.
If not, press disconnect and change the port that the dialer
is accessing.
