For specific digital fax/data setup procedures, see Appendix A - How to Setup Your PC Serial
Ports for Phonecell Digital Fax/Data.
Sending Digital Fax
Once the SX4e is set up as a Standard 19,200 bps Modem, no special mode setting on the terminal
is required to send a digital fax. After the PC fax program (WinFax, Netfax, etc.) is configured to
access the communications (COM) port where the SX4e is connected, the fax emulator will initiate
dialing through this COM port and the SX4e will automatically respond and dial the number.
Receiving Digital Fax
Once the SX4e is set up as a standard 19,200 bps modem, there are two command options for
receiving digital fax by a PC fax program. These options are programmed by going off-hook with a
DTMF telephone connected to the SX4e and entering the following commands:
1) Press
* *
9 4
to set "always on" receive digital fax mode, wait for dial tone, and go on-hook.
This command routes all incoming calls to the DB-9 serial port, not the RJ-11 port, and prepares
the SX4e to receive digital fax signals which are recognized by the PC fax program. When done
receiving digital fax calls in "always on" mode, reset the SX4e to default mode by entering the
command
* *
9 3
. All incoming calls are then routed to the RJ-11 port as voice calls.
2) Press
* *
9 7
to set "one time" receive digital fax mode, wait for dial tone, and go on-hook.
This command routes only the next incoming call to the DB-9 serial port, not the RJ-11 port, and
prepares the SX4e to receive digital fax signals which are recognized by the PC fax program.
After receiving the next call, the SX4e automatically resets to default mode and incoming calls
are routed to the RJ-11 port as voice calls.
Sending E-Mail, Browsing the Internet, or Sending Digital Data
Once the SX4e is set up as a standard 19,200 bps modem, no special mode setting on the terminal
is required to send an e-mail, browse the Internet, or send a digital data message (via HyperTerminal,
etc.). After the PC is configured to access the communications (COM) port where the SX4e is con-
nected, the PC will initiate all dial-up sessions through this COM port and the SX4e will automatically
respond and dial the number.
