Software/Driver Installation (SCO Open Server)
MultiModemISI Hybrid Server Cards, ISIHP & ISIHI Series 63
does not load, none of its ports will be accessible. (If this happens,
see Multi-Techs Administrative Utility section in this manual.)
2. Type the complete name of the first device you want to create in
usr/lib/uucp/Devices. Substitute the specific base name,
board number, and port letter for the generic parameters in the
expression ttylbx. Use a lower-case x value for local DTE
(terminal) support and an upper case X value for modem control for
each port you want to enable. Example: ttyl2A denotes the
second ISI card (2) and the first port on that card (A). The port
status can be altered later, but one setting must be selected at this
time. The ACU line would read as follows:
ACU ttylbX - 9600 dialer name . Replace b, X and
dialer-name with appropriate values.
3. Repeat this process for each port on each board you have installed.
Record the setting you select for each port.
4. Using device names created in the previous section, type the
following command for each port you want to activate: enable
ttylbx
5. Repeat this command for each port you want to activate, using the
lower case letter for local terminal use or upper case for modem
control.
Note: Only one of the options (e.g., modem control or local
terminal access) should be enabled for any port at one time. For
example, you cannot enable ttyl1a and then enable ttyl1A .
To change the status of a port, disable the current status
( disable ttyl1a ) and then enable it for the desired status
( enable ttyl1A ).
Removing the Driver (SCO Open Server 5)
To remove the Multi-Tech Serial Card Driver, enter the configuration
utility (e.g., custom for SCO Open Server 5) and follow instructions to
remove the entire driver and rebuild the kernel without the ISI driver.
If it is necessary to reinstall the driver due to I/O address or IRQ
overlap, remove the driver first.
Note: Remove the driver before permanently removing the ISI card from the
computer.
