Re: [gentoo-user] where is /dev/ttyS* ?

[Alan E. Davis]

I don't know whether this is off or on topic, but I noticed that my
modem was assigned to a different ttySX w/ 2.6.16.  I ran wvdialconf
again, which identified the new /dev/ name, and it has worked
flawlessly since.  2.6.X kernels have given me, at least, fits over
/dev/ttySX.  The /dev/ttyS device nodes are attached to /dev/tts/X .

I don't know whether any of this is valid for anyone else or not. 
Perhaps it's something idiosyncratic about my setup.
