SCO UNIX Built-in Serial Driver Installation Guide
for Moxa 4 Ports ISA Multiport Board
Applicable Products: A104, C104+, C104P, C104H, C104HS, C114P, C114HI, CI-134,
CI-134I,
CI-134IS, CI-104J, CI-104JS.
This document intends to support Moxa 4-port board, such as C104P, to
run under SCO UNIX and SCO OpenServer system.
Hardware Configuration:
- For A104, C104+ and C114P users, please ignore step 2, 3, 4, 6, 7.
- Short JP1 of C104P, plug it into PC and power on this PC under DOS environment.
- Execute ¡§IO-IRQ.EXE¡¨ to change its configuration.
- Input ¡§A700¡¨ as CAP address to enter the
setup display.
- For C104P, C104H, C104HS and C114HI:
Press ¡§F3¡¨ to
select OS compatibility and you can find there are 2 kinds of settings for SCO UNIX as
choice:
*SCO UNIX 1: Arnet
compatible, I/O base 0x280, IRQ 4, vector 0x2C2.
*SCO UNIX 2: Arnet compatible, I/O
base 0x180, IRQ 3, vector 0x1C2.
Choose a proper one as the configuration, we assume the first settings
are selected to configure C104P.
For A104, C104+ and C114P:
Find out available resource for I/O address, IRQ, and INT vector as the
configurations, now we assume the configurations are listed as below.
I/O address: 280, 288, 290, 298
Speed: all to normal (maximum speed
is up to 115.2 Kbps)
IRQ: all to 4 (4 ports share the
same IRQ)
INT vector: 0x2C0
- Press ¡§F10¡¨ to save this configuration
and quit ¡§IO-IRQ.EXE¡¨.
- Power off PC, set JP1 open and prepare to install C104P under SCO UNIX system.
Driver and System Configuration:
- Under SCO UNIX, enter ¡§mkdev serial¡¨ at command prompt to begin the driver and system installation.
- Because C104P has the settings of ¡§SCO UNIX 1¡¨, the IRQ will be 4, the same as COM1 or COM3.
Please check if any devices with the description ¡§interrupt = COM1¡¨ or ¡§interrupt = COM3¡¨ is listed on the screen. If yes, please press ¡§r¡¨
to choose ¡§r)emove an existing board¡¨ to remove it first. Or go back to Step 5 to
configure the C104P with the settings of ¡§SCO UNIX 2¡¨.
- Press ¡§i¡¨ to choose ¡§i)nstall a new serial board¡¨.
- Select ¡§1.
Standard tty device¡¨.
- Select ¡§3. 4
port card¡¨.
- When system asks you to input IRQ setting, the message ¡§The card is configures as¡¨ will appear on the screen. Because C104P has the settings
of ¡§SCO UNIX 1¡¨, please select ¡§1. COM1¡¨.
- Choose "2. Arnet base address 0x280".
- When system asks you to input baud rate for the C104P, input a proper value, for
example, 9600.
- Then system will ask you to create a new kernel or not, please press "y"
to create the new kernel.
- Reboot SCO UNIX to finish the installation process, the C104P will work properly under
SCO UNIX.
