Hi,
The command lslpp -h show me a lot of info, several programs was installed on that dates.
Looked in the inittab with no success, used fuser and found the program that use the tty, but nothing could found besides of that, configuration or other relevant info.
Also helped the use of ps -ef

Once found the relevant info, I opened a new question about GPS and tty Parameters
Connect GPS to serial port AIX 5.x

I consider bouth questions succesfully answered and closed

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. FILES
