Receiving a Fax Using Function Calls for
Noninfopkt-Formatted Raw G3
Files
One way to receive a fax using function calls for
noninfopkt-formatted raw G3 files is demonstrated below. Each
function is presented in sequential order, and the action it performs
is described beneath it.
This example receives fax data into a buffer only and does not
include instructions for further processing the contents of the buffer.
BT_ZERO(args_admin);
args_admin.unit = unit;
lp = BfvLineAttach(&args_admin);
Attaches to a free channel and gets a BTLINE pointer.
args_admin.config_file_name = "usrcnfig.cfg";
BfvLineReset(lp,&args_admin);
Resets the channel and sets the user-configured options in the
user-defined configuration file usrcnfig.cfg.
BT_ZERO(args_tel);
args_tel.timeout = 0L;
BfvLineWaitForCall (lp, &args_tel);
Waits for the detection of an incoming call.
BfvLineAnswer (lp, &args_tel);
Answers the phone line by going off-hook.
