I checked the pinout referenced by dalen in an earlier post, it looks
like laplink transfers data in 5 bit chunks.  That's all that is
available as input to a standard parallel port.  

A screen dump would, ideally, require an 8 bit byte per character, but
you could probably get away with 6 (all caps and no graphics).  Anyway,
a laplink crossover cable would not do well, even if there existed
software to receive the data.

Does anyone know if an ECP/EPP parallel port can be put into 8 bit
bi-directional mode?  If so, a userspace parallel port utility should be
possible to grab a screen dump and display or save it.
