maybe... your question really isn't all that clear.
You might mean with regards to some kind of network remote access to the console head (which would be my favorite guess on this).
In that case, a serial console device is like an Avocent/Cyclades applicance that allows multiple machines to connect via serial cables to that applicance and then you are able to use ssh (for example) to go to the applicance and establish a serial session to the connected hosts. I like this and use this style for a lot of out of band stuff...
Then the IP console solution would likely be some kind of KVM over IP or some kind of access directly to some kind of IPMI like thing (doens't have to be a standard IPMI, could be Sun's ALOM/ILOM, HP's ilO, Dell's DRAC, etc). The IP support through that (the latter IPMI-like case) could come in a myriad of forms... could be some kind of web based access... might fire up a Java based app for the console, etc.).
so... here's hoping I guessed correctly... your question could mean many things!!

iscc(7) Miscellaneous Information Manual iscc(7)
NAME
iscc - serial communications interface
SYNOPSIS
controller iscc0 at isa0
DESCRIPTION
An onboard Zilog 8530 DUART provides AXPvme-based Single Board Computers with console (CON) and auxiliary (AUX) serial communications
ports. Both serial communications ports can operate at baud rates from B50 to B38400, excluding B134 (see tty(7)).
On AXPvme Single Board Computers configured with a graphics head as the system console, the CON serial communications port (/dev/tty01) is
available for use by application programs as an additional communications port.
In the absence of a graphics head, the CON serial communications port (/dev/console) becomes the system console. When used as the serial
system console, the CON serial communications port always operates at 9600 BPS, 8-bits, and no parity.
Regardless of system console, the AUX serial communications port (/dev/tty00) is always available for use by application programs.
RESTRICTIONS
Data communications equipment attached to the CON serial communications port must be set to 9600 BPS, 8-bits, no parity when configured as
the serial system console. The iscc terminal driver enforces this restriction.
No modem control is supported for either the CON or AUX serial communications ports.

console terminal local terminal local terminal
