NetBSD 6.1.5 - man page for tcom (netbsd section 4)

TCOM(4) 			   BSD Kernel Interfaces Manual 			  TCOM(4)

NAME
     tcom -- multiplexing serial communications interface

SYNOPSIS
     For 4-port TC-400 series boards:

     tcom0 at isa? port 0x100 irq 5
     com2 at tcom? slave ?
     com3 at tcom? slave ?
     com4 at tcom? slave ?
     com5 at tcom? slave ?

     For 8-port TC-800 series boards:

     tcom0 at isa? port 0x100 irq 5
     com2 at tcom? slave ?
     com3 at tcom? slave ?
     com4 at tcom? slave ?
     com5 at tcom? slave ?
     com6 at tcom? slave ?
     com7 at tcom? slave ?
     com8 at tcom? slave ?
     com9 at tcom? slave ?

DESCRIPTION
     The 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).
