I have this really neat 8 port serial / 2 port printer device that
says "AT&T IPC 802" on the case.

It has a 16 bit interface card with 10 small chips on it and two 8
switch blocks.  It has an IRQ jumper bank with IRQ15,14,12,11,10,7,
6,5,4,3,2 positions and a 37 pin connector that runs to the I/O box.

The box is about 11 x 17 inches and 1 inch thick with 8 serial rs232c
and 2 parallel 25 pin connectors.  This unit is boldly labled "AT&T

I was just going to throw it out 'till I opened it to find 2 Z80 CPU's,
128K of 12ns ram and several support chips.  I know it's not super high
tech but it should be able to rune the 8 serial lines pretty well...

I don't have the original docs for it but I have the disks with the
DOS drivers :(

Inside the box I found information on the board indicating the original
manufacturer.  CTC Systems, INC.  P/N 30200A Gemini-10 871107.

I have looked at all the drivers that come with the linux source and
have looked at sunsite for other drivers that may work.  I even
tried the cyclades just for kicks (No luck).

Any help finding a driver or docs or a contact for CTC Systems would
be very helpfull.

Thanks (rstup...@oingomth.uwc.edu)

To load the IPC.DRV, you must:

1. Modify (or create) the CONFIG.SYS file on your boot disk to include:

   DEVICE=IPC.DRV [options]


   the "options" is up to four groups of /<IO addr>,<ram addr>,<board type>,
   (board type = 0 for IPC900 and 1 for IPC802)

        DEVICE=IPC.DRV /290,D0000,0 /2A0,D2000,1 /2B0,D4000,1 /2C0,D6000,0

        specifies four IPC boards installed.
        The configuration of the IPCs is as follows:

      1      290 (HEX)        D0000 (HEX)      IPC900  SIO1  - SIO8
      2      2A0              D2000            IPC802  SIO9  - SIO16,PPO3,PPO4
      3      2B0              D4000            IPC802  SIO17 - SIO24,PPO5,PPO6
      4      2C0              D6000            IPC900  SIO25 - SIO32

   The first and the fourth boards are IPC900 where the second and the third
   one are IPC802. If omitted, then the default is one IPC900 board with
   factory address setting (/290,D0000).

2. Copy the IPC.DRV file to the root directory of your boot disk.

3. Re-boot your system.

Once IPC.DRV is loaded, you can use the Serial Input Output ports or the
Parallel Printer Output ports (IPC802 only) on the IPC board as if they
were files with file names SIO1, SIO2, ..., SIO32, and PPO1, PPO2, ..., PPO8

To change the BAUD and data format of the Serial Input Output ports, use the
command GMODE.  GMODE uses simular syntax as the DOS command MODE.  e.g.

          GMODE SIO3:1200,E,7,2

where the serial I/O port SIO3 has been programmed to the
following parameter: 1200 baud, EVEN parity, 7 Data Bits per
Character, and 2 Stop Bits per character.

          GMODE LPT1:=SIO3

redirects the output to the parallel output port LPT1 to IPC serial port

          GMODE LPT1:

restores the parallel output port LPT1

4. To output any ASCII data to any one of the 40-ports:

        COPY    filename  SIO1
        COPY    filename  SIO2
        COPY    filename  SIO32
        COPY    filename  PPO1  (IPC802 only)
        COPY    filename  PPO2
        COPY     filename PPO8

5. To input from any serial I/O ports (PPOx are output Parallel Printer ports

        COPY    SIO1  filename
        COPY    SIO2  filename
        COPY    SIO32 filename

    Note: any input typed on the CRT terminal corresponding to
          the SIOx port will not echo on the CRT Terminal screen. The
          file specified by the filename must be closed by enter a Ctrl-Z
          from the CRT Terminal keyboard.

6. To make one of the SIOx ports as the PC console input & output

        CTTY    SIOx

7. To switch the console functions back to the PC Monitor &
Keyboard by entering the following on the CRT Terminal keyboard:

        CTTY    CON

8. To access the IPC from application programs by first
open SIOx or PPOx as a file with appropriate parameters such as
input sequential, output sequential, Random Access, etc. to
obtain a file ID. At any time when accesses to these ports are
needed, the file READ and file WRITE statements can be used. And
of course the same ports have to be CLOSED at the end as well.

9. One can also access the Serial Input Output ports (SIOx) through BIOS INT
14H calls.  Follow the same protocals as the COM1 and COM2 BIOS INT 14H calls
with the following exception:

a. DL=80H for the first IPC board, DL=81H, 82H, or 83H for the second,
   third or fourth IPC board respectively.  COM1 and COM2 can still be
   accessed with DX=0000H and 0001H respectiovely.

b. DH=0 for the first serial port on the selected IPC900 board, DH=1, ..., 7
   for the second through eighth serial port on the selected IPC board.

   DX=0080H -> SIO1   DX=0180H -> SIO2   DX=0280H -> SIO3   DX=0380H -> SIO4
   DX=0480H -> SIO5   DX=0580H -> SIO6   DX=0680H -> SIO7   DX=0780H -> SIO8
   DX=0081H -> SIO9   DX=0181H -> SIO10  DX=0281H -> SIO11  DX=0381H -> SIO12
   DX=0481H -> SIO13  DX=0581H -> SIO14  DX=0681H -> SIO15  DX=0781H -> SIO16
   DX=0082H -> SIO17  DX=0182H -> SIO18  DX=0282H -> SIO19  DX=0382H -> SIO20
   DX=0482H -> SIO21  DX=0582H -> SIO22  DX=0682H -> SIO23  DX=0782H -> SIO24
   DX=0083H -> SIO25  DX=0183H -> SIO26  DX=0283H -> SIO27  DX=0383H -> SIO28
   DX=0483H -> SIO29  DX=0583H -> SIO30  DX=0683H -> SIO31  DX=0783H -> SIO32

c. Returned Status does not reflect real-time status of the UART due to
   hardware differences and the use of on-board input and output buffers.
