SX5T CDMA 11 User Manual
Digital Fax Setup
The SX5T is capable of receiving and sending faxes via a personal computer using a serial or
USB port. The PC application and modem setup must be able to support software flow control.
To setup flow control properly, follow the instructions for setting up a standard modem connection
in Appendix A of this manual with the following changes.
HINT: Set up separate modems for PC fax and PC circuit switched data connections. This way
you will not have the make changes to the modem settings everytime you want to switch
between fax and data.
1. Change the flow control of the standard modem to enable software flow control.
2. Change Extra Settings from AT&D1 to AT+IFC=1,1 &d1. This enables software flow control on
the SX5.
3. To deliver faxes to your computer’s USB port, set the SX5T to USB data connection by
entering # * 67 * 3 #.
4. Run your PC fax application using this new modem connection for receiving and sending
faxes.
HINT: To set the SX5T to receive fax calls through its RJ-11, press # * 67 * 1 #.
Analog Modem Support
The SX5T supports connectivity with an analog modem.
RJ-11 Port Setup
The RJ-11 voice jack on the SX5 (the jack marked with a phone icon) can be configured for
voice (default setting) or analog modem data. If the jack is configured for analog data, the
bypass string for voice calls must be entered before a voice call can be made. In voice mode,
data transmissions are routed through the data port. To send data via an analog modem while in
voice mode, use the analog bypass string.
Modem Connection Options
The SX5T has the capability to either wait for a remote modem to connect before the local modem
connects or not. If your application has timing issues where the local application times out before
the remote modem connects, then use the following string command to enable this option.
Press: #

Bypass String
Enter the bypass string if you want to make a single call in a different mode than the current
mode. After the call, the SX5 will return to the mode that was active before the call.
