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 subde‐
     vices and the port for the interrupt multiplexing register.

     Not all possible configuration options are currently supported (for exam‐
     ple, speeds beyond 115200 baud are not currently supported).
