The printer.device obeys when you set the WindowPtr in your process
structure to -1; in this case it does not bring up the requester,
instead returning to let the program handle things.

Second, left-Amiga V and left-Amiga B can be used to retry and
cancel autorequesters respectively anyway, without the mouse.

(there are keyboard equivalents for other mouse functions; no one
said they were fun though; either Amiga key and the cursor keys
control the mouse movements; either Amiga key and the left Alt is
the left mouse buttom; either Amiga key and the right Alt key
is the right mouse button.)

Just so you know...

I think the SERIAL_QUERY command will give you what you want.
