Installation.
packet: a QMR packet, (see chapter 7, Scanner Management) into
which setup_6008 returns the autoconfigure information, or status in
case of error. Note that the argument is a pointer to the packet.
Returned values:
status: an integer: SC_OK 0(hex) if the setup proceeded without error,
C_AUTOCONF 10(hex) if the initial autoconfigure failed, C_SETUP
13(hex) if the setup call (changing baud rate or resistor) failed; any
other value means that the initial sync with the scanner failed.
If the returned value is SC_OK, your program’s packet contains the
information regularly returned by an autoconfigure.
If the returned value is anything but SC_OK, the specific nature of the
error is in the qmr_stat field of the packet that you passed to
setup_6008. Your program should display status information and abort
immediately.
Here’s the start of a sample program, showing a call to setup_6008 and
associated checks for error:
#include
#include
void main( )
{
QMR pkt;
int status;
. . .
status = setup_6008(-1, -1, -1, 0xC400, &pkt);
if ( status != OK ) {
printf(“setup failed: command=%s status=%s\n”,
xlat_cmd(status), xlat_conf(pkt.qmr_stat));
if ( status != C_AUTOCONF && status != C_SETUP )
printf(“scanner fatal error %d\n”, fatal_6008(
));
abort( );
}
else
mr_print(stdout, C_AUTOCONF, &pkt);
. . .
The declaration, QMR pkt, is explained in chapter 7, Data Structure.
