That isn't strictly true.

I am intrigued. Other than the valid baud rates what differences are visible at the user level?

For me, it would also simplify the issue of trying to work what devive to
look for when I plug in a new USB serial port device. It would be the new
/dev/ttyS<x> to appear in /dev.

Naming is a private matter for udev anyway, independant of numbering for

Yes, but I have not found a simple way to configure it to add serial port devices to the next available /dev/ttyS<xx>. If this was the default, it would be much easier for me :). (I am assuming that all the different serial port devices I use are transparent at the user level, hence my question above.)
