I'm guessing that "a Linux Enterprise 3.0 server" is some sort of Red Hat 
system. If it is typical of Linux systems, you need a line in /etc/inittab 
that looks something like this (this is an example taken from a Debian 
system) --

         T1:23:respawn:/sbin/getty -L ttyS1 9600 vt100

You need the right entry for the serial port you are using (ttyS0 or ttyS1, 
on usual systems). The rest of the details will vary depending on which 
*getty program your system actually uses.

Aside from that, you need to make sure

         that the serial port is enabled in the system's BIOS (aside from 
checking the actual BIOS settings, see if "setserial /dev/ttyS1", run as 
root, returns a UART type -- or ttyS0 if you're using that port).
         that your Linux kernel has serial-port support compiled in (check 
dmesg to make sure the serial ports are seen at boot).
         that you are using a crossover cable with whatever handshaking the 
systems expect.
         that Hyperterm itself is working correctly.
