Appendix F - Installing Under SCO OpenServer
Introduction
This appendix explains how to install a modem on a computer operating under the
SCO OpenServer 5.0.x operating system. Briefly, in SCO OpenServer , you do not
need drivers for most modems. Programs in SCO OpenServer commonly call upon
the port, rather than the modem.
Installation
Install the MultiModemZPX in the computer as described in Chapter 2.
Setup
1. Turn on the computer and allow the computer to boot to the command prompt.
2. Log in as root.
3. Determine the port address and IRQ for the modem by typing: hw -r pci
To output the port address and IRQ information to a file, type: hw -r pci>pci.txt
Caution: If you choose to output the information to a file, make sure the output
file name includes the .txt extension. While logged on as “root”, the possibility
exists that the system file “pci” will be overwritten. By default, UNIX does not
ask if you want to overwrite a file.
4. Look at the ClassCode: 0x078000 (other communications device) section of the
output. The MultiModemZPX is identified as SubSystemID: 0x0480.
5. Use the first I/O address listed as the port address. In the output, look for:
BaseAddr [x]: I/O NxNNNN
where x is the first I/O base address (not memory) and NxNNN is the I/O address.
6. Use Serial Manager (or mkdev serial) to add a serial port. Choose IBM Com X
for the new port, where X is the number of the new port. Use the first I/O ad-
dress listed in the output file created in step 3 (BaseAddr [x]:) as the port address.
7. Use the IRQ listed in the InterruptLine of the output file created in step 3.
8. Once the serial port has been added, the system will require the kernal to be
relinked. After the relinking is complete, restart the system to activate the changes.
9. Log back on as root.
10. At this point, you may configure the modem as needed on the new port and add
required entries to Devices.
11. Once you’ve completed your hardware installation and system setup, you must
configure your modem for country-specific operation. Refer to Chapter 2 for in-
formation on using AT commands to configure the modem for use in your country.
Note: If you are using the modem to dial out, a dialer may be needed.
