Installing Dflex Boards under SCO Unix 3.2.2 Open Server Enterprise
This tech note details how to install Dflex boards under SCO Unix 3.2.2 Open Server Enterprise. All configurations assume that the target machine has two serial ports installed at 0x3f8 and 0x2f8 on interrupt lines 4 and 3, respectively.
Various configurations are presented, if none of the configurations match your setup, contact CTI Tech Support.
Dflex-2 as COM3
This setup involves installing a Dflex-2 adapter as the third and fourth serial ports in the system. Using SCO terminology, the board will be installed as COM3.
1) Install the board in the machine set with base address 0x190,
IRQ 10, status port enabled:
- Sw 1-1 Off
- Sw 1-2 Off
- Sw 1-3 Off
- Sw 1-4 Off
- Sw 1-5 Off
- Sw 1-6 Off
- Sw 1-7 On
- Sw 1-8 On
J1: A-10
2) The following line(s) must be added to the file:
/etc/conf/pack.d/sio/space.c:
{0,STARGATE, 2,10,0, (sd)0x190,0x190+STAR_POLL, 8,MCRBIT3}, /*AT-Dflex-2*/
{1,STARGATE, 2,10,8, (sd)0x190,0x190+STAR_POLL, 8,MCRBIT3}, /*AT-Dflex-2*/
{2,STARGATE, 2,10,4, (sd)0x190,0x190+STAR_POLL, 8,MCRBIT3}, /*AT-Dflex-2*/
{3,STARGATE, 2,10,12, (sd)0x190,0x190+STAR_POLL, 8,MCRBIT3}, /*AT-Dflex-2*/
BEFORE the line that says:
{-1, MC}, /* Boards for Micro Channel Architecture */
3) Run “mkdev serial”. When asked what type of board to install,
select a 2 port on COM3.
Dflex-4 as COM3
This setup involves installing a Dflex-4 adapter as serial ports 3 through 6 in the system. Using SCO terminology, the board will be installed as COM3.
1) Install the board in the machine set with base address 0x190, IRQ 10, status port enabled:
- Sw 1-1 Off
- Sw 1-2 Off
- Sw 1-3 Off
- Sw 1-4 Off
- Sw 1-5 Off
- Sw 1-6 Off
- Sw 1-7 On
- Sw 1-8 On
J1: A-10
2) The following line(s) must be added to the file: /etc/conf/pack.d/sio/space.c:
{0,STARGATE, 4,10,0, (sd)0x190,0x190+STAR_POLL, 8,MCRBIT3}, /*AT-Dflex-4*/
{1,STARGATE, 4,10,8, (sd)0x190,0x190+STAR_POLL, 8,MCRBIT3}, /*AT-Dflex-4*/
{2,STARGATE, 4,10,16, (sd)0x190,0x190+STAR_POLL, 8,MCRBIT3}, /*AT-Dflex-4*/
{3,STARGATE, 4,10,12, (sd)0x190,0x190+STAR_POLL, 8,MCRBIT3}, /*AT-Dflex-4*/
BEFORE the line that says:
{-1, MC}, /* Boards for Micro Channel Architecture */
3) The file /usr/lib/mkdev/perms/SER must be changed to align the minor numbers with space.c. The original portion of the SER file appears as follows:
#
SER3 c666 bin/bin 1 ./dev/tty3a 5/4

4) Run “mkdev serial”. When asked what type of board to install, select a 4 port on COM3.
Dflex-8 as COM3
This setup involves installing a Dflex-8 adapter as serial ports 3 through 10 in the system. Using SCO terminology, the board will be installed as COM3.
1) Install the board in the machine set with base address 0x190, IRQ 10, status port enabled:
- Sw 1-1 Off
- Sw 1-2 Off
- Sw 1-3 Off
- Sw 1-4 Off
- Sw 1-5 Off
