Yes & no.
It would put a limit on the number of ports of a type you could have
without having a discontinuity in the numbering when you use the default
macppc used to have tty00 and tty01 be the zstty serial ports, and tty10
was a com serial port. That leaves room for 8 zstty serial ports w/o
having to skip around. If you do skip 10 throuh 19, you then have the
whole field open.
It's not been my experience that folks add a lot of zstty or com serial=20
ports. Thus I don't think tty00/01/10 naming is an issue. If you are=20
adding more than ten of either, you have to roll your own MAKEDEV, so the=
numbering isn't that big a deal.
