tty usually means a serial port device file in AIX, like Zaxxon said, you normally can found something like /dev/tty0 or /dev/tty1. A tty device can be config as a rs-232 port, rs-485 port, or asyn device. It's also can be define as a console port.
console is concept of control terminal. could be a physical device or just a logical term. Physically, in most UNIX, you can define a console via a serial port like one of tty and connect a software or hardware terminal to control a station, or use your video card, in Power System you can use a HMC. Also you can define a logical console in software to redirect your in put output information.

Is there a utility built into Solaris that will allow me to see console messages from a tty?
I've done a search and see that this is possible through software like ILOM, but I'm looking for a method to do this with built in utilities.
For example, on AIX, I can use swcons `tty` (6 Replies)

scc(7) Miscellaneous Information Manual scc(7)
NAME
scc - Serial keyboard/mouse/communications interface
SYNOPSIS
controller scc0 at tc0 slot 3 vector sccintr
DESCRIPTION
Two base board Zilog scc dual UARTS provide DEC 3000 series personal systems with keyboard, mouse, and serial communications interfaces.
The serial communications interfaces can operate at baud rates from B50 to B57600 (see tty(7)).
The driver for the scc interface supports hardware flow control using the Request to Send (RTS) and Clear to Send (CTS) signals. When
hardware flow control is enabled, the flow of input data is controlled by the RTS signal and the flow of output data is controlled by the
CTS signal. If the CTS signal is off, the driver will suspend output to that line until the CTS lead is reasserted. Likewise, the driver
will turn off the RTS lead to tell the device connected to the line to stop sending data as a result of congestion on the host side. When
the condition clears, the driver will turn on the RTS lead to tell the device to resume sending data.
In alternate console configurations (that is, no graphics head), communications port 2 (/dev/tty01) becomes the system console. The serial
system console port always operates at 9600 BPS, 8-bits, no parity. No modem or hardware flow control is supported.
RESTRICTIONS
Data communications equipment attached to the console serial port in alternate console configurations must be set to 9600 BPS, 8-bits, no
parity. The scc driver enforces this restriction.
Only communications port 1 (/dev/tty00) includes full modem control.
