But that's only relevant if the capacitor is important.

A board tends to have lots of bypass capacitors, and missing one or a few
may not affect operation, certainly shouldn't cause a total failure.

There won't be much in the way of non-bypass capacitors on a serial board,
there just isn't any need for them.  The only exception would be if there's
an onboard crystal oscillator for  baud timing, there would be one or two
capacitors around the crystal, and maybe if one of those were missing there'd
be a problem (since it might not oscillate, or it might possibly oscillate
too far from the needed frequency to cause problems (though that's only
slightly possible).
