Line 356 to 359 of /sys/arch/amiga/dev/ser.c check if "hupcl" is asserted.
If it is not asserted, then the modem lines are _not_ to be changed.
For some reason, these lines are between an #if 0/#endif pair.  I removed
the "#if 0/#endif" and now hupcl works as it should.  Now I'm wondering
why it was disabled in the first place...

The mentioned #if  0 were in our source tree from the beginning; I guess 
because part of the cleanup must be done even if HUPCL is not set. 
We set the other bits to 0, but leave DTR alone if HUPCL is not set.  
Furthermore, we sleep for a small while after resetting bits, so that they will 
be recognized even if we are reopened immediately after returning from close.
