I got Guide8 to slew using ASCOM. It appears I omitted to select the tracking rate on the ASCOM Driver Handbox. Also I think having a '4' in the little box to the right of 'other' helps. I presume this is the COM port number. My Prolific USB to Serial converter uses COM4.

Still not working on the Astro-Physics setting. I tried connecting the AP keypad, but made no difference.

Thanks for the help,
John
