Yes. Serial-over-LAN is a feature on many IPMI-equipped systems. I believe
both the OpenIPMI-tools and freeipmi packages have a means by which to
connect to them, but I'm not all that familiar with either one myself.

$ rpm -qf /usr/sbin/ipmiconsole
freeipmi-0.5.1-3.fc9.x86_64

$ ipmiconsole --usage
[...]

$ rpm -qf /usr/bin/ipmitool
OpenIPMI-tools-2.0.13-2.fc9.x86_64

$ ipmitool -h 2>&1 |grep sol
 sol       Configure and connect IPMIv2.0 Serial-over-LAN
 tsol       Configure and connect with Tyan IPMIv1.5 Serial-over-LAN
 isol       Configure IPMIv1.5 Serial-over-LAN
