[sudo-discuss] null modem adaptor needed

[Jake]

unfortunately a gender changer is unlikely to also be a null-modem adaptor 
unless it says so on there.. in which case we would need another gender 
changer since presently the gender is correct..

which is funny because usually gender and DTE/DCE are correlated, so you 
need neither or both.  But if we don't have one the next time i am there, 
i will just make a null-modem cable.
