OPENING PORTS OTHER THAN 80 Apache/1.3.31 Server

Windows?  Linux?

88 is generally a port reserved for use by Kerberos.  For my example below, I've used 8088

For the Apache portion of the configuration, you'd simply add:

Listen 8088
NameVirtualHost xxx.xxx.xxx.xxx:8088

<VirtualHost xxx.xxx.xxx.xxx:8088>
...
</VirtualHost>

where xxx.xxx.xxx.xxx is your IP address.

On a Linux server, you'd also add an appropriate line to the /etc/services file

Under Windows, I'll let someone else respond :)

Even easier under Windows!
- Same as already pointed out by Periwinkle for Linux, though on Windows you need to edit only one line in your httpd.conf file (can be found in your apache conf directory)

- Change 'Listen xxx.xxx.xxx.xxx:8088' to 'Listen xxx.xxx.xxx.xxx:8088' (substitute the Xs with your IP address)

- The next line 'Listen 80' should be commented out (# Listen 80)
- Don't forget to restart apache after editing httpd.conf :-)

Good Luck!

I would think that these should work just fine.
