A file transfer protocol sets up the ground rules that your modem
and the remote system will use to get files back and forth. Your
communications software manual will describe the various
protocols it supports. Your communications software will usually
walk you through the download/upload process.
Fax Operation
Fax software essentially turns your computer and modem into a
fax machine and allows you to send a file to or receive a file
from another fax modem or fax machine.
Similar to your communications software, your fax software uses
basic AT commands for functions such as dialing and answering
calls and for speaker control and adjustments. Refer to your
communication software’s user’s guide for more information on
AT command support.
Before sending or receiving a fax, verify the following:
G
Your modem and PC must be configured for modem
operation before executing your fax software.
G
You must have fax software installed on your PC. (For
the KeepInTouch Card modem, if sending or receiving a
fax, the software must be operating.)
G
Some fax software packages require the modem to have
Auto-Answer disabled (S0 = 0) to receive a fax.
G
Some fax software packages require that the modem
use software flow control (\Q) to send and receive a fax.
Refer to your fax software documentation for more on fax
operation.
Using Cellular Channels
Some models of the KeepInTouch Card modem can transfer
data over cellular communication channels. For more
