Using -dlpt and -dserial at the same time isn't going to work like
you've done it. You can use either "-dlpt=/dev/ttyS0" or
"-dserial=/dev/ttS0". Uisp knows it is a serial dongle from the
"-dprog=dasa" option.

What you've told uisp to do is open the "serial" device file in the
current directory and the -dserial option is ignored since giving -dlpt
will cause uisp to ignore the -dserial option.

Clear as mud, no? ;-)
