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:

  1. For A104, C104+ and C114P users, please ignore step 2, 3, 4, 6, 7.
  1. Short JP1 of C104P, plug it into PC and power on this PC under DOS environment.
  1. Execute ¡§IO-IRQ.EXE¡¨ to change its configuration.
  1. Input ¡§A700¡¨ as CAP address to enter the setup display.
  1. 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

  1. Press ¡§F10¡¨ to save this configuration and quit ¡§IO-IRQ.EXE¡¨.
  1. Power off PC, set JP1 open and prepare to install C104P under SCO UNIX system.


Driver and System Configuration:

  1. Under SCO UNIX, enter ¡§mkdev serial¡¨ at command prompt to begin the driver and system installation.
  1. 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¡¨.
  1. Press ¡§i¡¨ to choose ¡§i)nstall a new serial board¡¨.
  1. Select ¡§1. Standard tty device¡¨.
  1. Select ¡§3. 4 port card¡¨.
  1. 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¡¨.
  1. Choose "2. Arnet base address 0x280".
  1. When system asks you to input baud rate for the C104P, input a proper value, for example, 9600.
  1. Then system will ask you to create a new kernel or not, please press "y" to create the new kernel.
  1. Reboot SCO UNIX to finish the installation process, the C104P will work properly under SCO UNIX.
