Subject: Directly accessing serial ports from drivers w/o TTYs ?

Hi folks,

is there already a way for accessing serial ports from drivers,
w/o having to go through the TTY subsystem ?

Serdev seems provide a connection between arbitrary TTYs to device
drivers. But this implies always having a TTY for each UART (even if
it's never used outside the kernel).

Is there any way for accessing uarts more directly ?
