Introduction
The software installation instructions below have been designed to assist users with the installation of various CTI multi-port serial adapter(s) under SCO Unix and Unix Open Server 5.0.X platforms. These instructions can be used in conjunction with Echo/Dflex ISA, DFlex PC/104 and Xtreme PC/104 lines of serial adapters, since all of these adapters require the same installation script.
To perform the installation, please be sure to be logged in as root. To make the instructions easy to follow, all commands that have to be issued on the command line are written in bold text.
Running The Installer
NOTE: It is often necessary to go into the CMOS setup (BIOS) and ensure that the IRQ used by the Echo/Dflex or Xtreme is available to Non-PnP ISA devices only. Look in the CMOS setup for Resource Configuration or PnP Setup options.
NOTE: The installer can be downloaded from the Knowledge Base.
NOTE: The installer, named install.Echo/Dflex comes tarred on the diskette.
To begin, you will have to untar the installer to a directory on your system. The location where you copy the file is not particularly important, however it is suggested that the file NOT be placed in the root directory. Usually a /usr directory is fine.
The directory you choose to copy the file to will now be referenced by {Installer}.
- To untar the installer (from the floppy drive), issue the following commands:
# cd {Installer}
# tar -xvf /dev/fd0/ NOTE: Make sure that install.Echo/Dflex has executable attributes. If not, issue the following command to change the access permissions:
# chmod 700 install.DFlex - Run the installer:
# ./install.DFlex - This will bring up the serial adapter’s installation menu. You will be asked to confirm your board’s IRQ, base address, and number of ports. Make sure the values you enter here match the hardware settings. Please refer to the manual for more information about hardware settings.
- After you have confirmed your board settings, you will automatically be brought to the mkdev serial utility. In this utility, you will add the CTI board.
- From the menu, hit the TAB key until it selects the ADD option.
- From the ADD option, you will be presented with a list of cards. Within the list, you will see an entry with the serial adapter you have just installed (either Echo/Dflex, Xtreme/104 or DFlex/104).
- Select the card and select OK.
- If you need to change the settings of the card, you can do so at this time.
- Select the exit option.
- You will be prompted by UNIX several times. Choose Yes at all of the prompts. Your kernel will now be rebuilt.
- After UNIX has finished building your new kernel reboot your system.
Testing the Newly Installed Ports
You can perform a simple loopback test with a terminal program (i.e. cu) and a loopback connector to ensure that the newly installed ports are functioning.
Connect the loopback connector to the port you want to test and run “cu”. When you type a character, you should see it on the screen, which means that the port is working. If you remove the loopback connector, the characters that you type should not appear on the screen.
Assuming that you want to test /dev/tty3a with cu, run:
cu -l /dev/tty3a -s 9600
