-inter sets the interactive mode for a bunch of other flags. Most are used
for selecting the protonation states of the termini and other residues. It
can also be used for interactive SS bridge selection.

Please note that changing the protonation states of the residues does not
mean you're performing the simulation at a "different pH". A proper
constant-pH MD simulation allows the residues to titrate in respect to the
solution pH as well as the their "molecular environment". In this case,
your residues will be "stuck" in a user defined protonation state that may
or may not reflect the most populated protonation states of those residues
at a given pH, irrespectively of their surroundings.
