CEC(4) BSD Kernel Interfaces Manual CEC(4)NAME
cec -- IEEE488 GPIB controller boards
SYNOPSIS
cec* at isa? port 0x2b8 irq 5 drq 1
gpib* at cec?
DESCRIPTION
The cec driver supports GPIB (IEEE488) controller boards based on the NEC uPD7210 GPIB controller chip. The following boards are supported:
- Capital Equipment Corp. IEEE488 board
- Keithley GPIB boards
The following GPIB boards are similar and support should be available reasonably easily:
- HAMEG HO-80 IEEE488 board
- National Instruments PCII board
- Measurement Computing (Computer Boards) ISA GPIB boards

The cec driver appeared in NetBSD 2.0.

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 regis-
ter 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).
