BT_ZERO(args_fax);

 

args_fax.fname = "memo.txt";

 

args_fax.fmt = DATA_ASCII;

 

BfvFaxSendFile(lp, &args_fax);

Sends the ASCII text file, memo.txt the only file on the second page, 

to the driver.

BfvFaxEndOfDocument(lp, &args_fax);

Indicates to the driver that the second page is the last page of the 

transmission.

BT_ZERO(args_admin);

 

BfvLineDetach (lp, &args_admin);

Frees all the memory for the attached line and closes the device.

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.
