The kernel configuration specifies these +.Nm com +devices as slave devices of the +.Nm +device, as shown in the synopsis. The slave ID given for each +.Nm com +device determines which bit in the interrupt multiplexing register is +tested to find interrupts for that device. +The +.Tn port +specification for the +.Nm +device is used to compute the base addresses for the +.Nm com +subdevices and the port for the interrupt multiplexing register. +.Sh FILES +.Bl -tag -width Pa +.It Pa /dev/tty?? +.El +.Sh SEE ALSO +.Xr com 4 +.Sh HISTORY +The +.Nm +driver was written by Charles Hannum, based on the +.Nm ast +driver and source code from David Muir Sharnoff.
