What do you think? True, but why make the job harder than it is? Michael has a good point too. And we have free bits, I don't see why we can't add one for "do what I said" (wrt. rts/cts), which, if unset means to do be in automatic mode and ignore the other bits. Or we really do use a two-bit field with values; 0 automatic 1 neither 2 rts 3 cts or something. johannes --=-BGszA72U+fNSA6hGNPy2 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIcBAABAgAGBQJJ55mYAAoJEKVg1VMiehFYB+sP/iWFsHYWRejVcMyUxMCnqk5C 0cyLKLkJJEelO3QsjBmgyIHI7fKCe+QsNsWsKn8HuHmIlRzXbace9K2rMVQ7I3O/ cs3ci2vYWy8MVjXST8SVjo0AKxGhVABeGxl3QyQoAU8mFhGCxgzGqke3nXC69Oeu UDBJyQFOvhDHSj5RYdPVbx9NBYM9HUSjSh4aK8Qxiblmmpx/OHrAX/q3YFOp6Qz7 v4bvBwhb/ivgfQO5SeUf0dyqsIlSTp4odWk8VB3JLjaR+MfNN+WsoQjFJu2qFKZm FSp4C9swjqRDop+WJCl++eUsPgC1fBSUN3+dXaDTKQV9nKBri52M9XNnCkk0Z50W 9SFobXo6r4/3wQtnc9yEptyDyKCebZi2AguoEu5kaIG432ok/TSmxeV+vaPokTlm sztxsHO3JmWnasNwVAI1q30T2yW67G3LBCkquAukM5pM2TsfCmAcrnsIsySUgcCi LvSuGDLAryA7LW3MDJSJj/K8cvfL/M3wdDibLoTXGY4oWJ6mblE88g/ST8BBNUpj aAgHmh/wVop/oOMOjqPAGKXkCMIqckO5cmeWJ+AgzTO3hC1mC8bQd1Uu6swIcjbM Nslh0TslFDTUAYaKexiMkZojacfW3WFYiYfmq7SMfMEpm2qFS/yvkqsGoMnTSmvh fULZp+98Mq7IzQWRbDLM =pJw9 -----END PGP SIGNATURE----- --=-BGszA72U+fNSA6hGNPy2--
