tcom driver provides support for the Byte Runner
  Technologies TC-400 and TC-800 series boards that multiplex together up to
  four or eight EIA RS-232C (CCITT V.28) communications interfaces.
Each tcom device is the master device for
    up to eight com devices. The kernel configuration
    specifies these com devices as slave devices of the
    tcom device, as shown in the synopsis. The slave ID
    given for each com device determines which bit in
    the interrupt multiplexing register is tested to find interrupts for that
    device. The port specification for the tcom device
    is used to compute the base addresses for the com
    subdevices and the port for the interrupt multiplexing register.
Not all possible configuration options are currently supported (for example, speeds beyond 115200 baud are not currently supported).
tcom driver was written by Jukka Marin.
