Sorry, yes the rationale was a big bit vague :-(

serial_open() provides a generic serial connection. Data that goes in 
one end, hopefully, comes out the other end - it doesn't promise to be 
reliable though.

remote.c, on the other hand, makes certain assumptions about the 
properties of the SERIAL object it is using (only data overrun is 
possible, single character transfers are reliable, ...).  Hence, I think 
remote.c should be the one reporting a potential problem.

Besides, if someone were to implement a remote-udp.c the warning would 
be wrong :-)

enjoy,
