struct pic_handle __attribute__

(

(__may_alias__)

)

int32_t pic_connect	(	char *	dev,
		pic_handle *	handle
	)

Connect to PIC.

Connect to a PIC speaking NMEA protocol, connected to the specified RS232 device, in preparation for querying it for position measurements.

Parameters

dev	Name of RS232 character device.
handle	Pointer to pic_handle.

Returns

Zero, or negative error number.

{
cssl_start();
if (handle->serial != NULL)
    return(PIC_ERROR_OPEN);

handle->serial = cssl_open(dev,PIC_BAUD,PIC_BITS,PIC_PARITY,PIC_STOPBITS);
cssl_setflowcontrol(handle->serial,1,0);
if (handle->serial == NULL)
    return (PIC_ERROR_PORT);

cssl_settimeout(handle->serial,1,.1);

handle->buffer.seq = 0;

return 0;
}

int32_t pic_disconnect

(

pic_handle *

handle

)

Disconnect from PIC.

Disconnect from previously connected PIC, closing associated serial device.

Parameters

handle

Pointer to pic_handle.

Returns

Zero, or negative error number.

{
if (handle->serial == NULL)
    return (PIC_ERROR_CLOSED);

cssl_close(handle->serial);
return 0;
}
