P520 AIX com port (tty0) settings

I have software running under AIX 5.3 that should communicate with a special device using standard communication protocol (Modbus) using serial RS-232 line

The settings are correct in both sides, But I can't establish a connection.
I suspect that there's something that I should do regarding the tty0 ...

(screen shot of tty0 are attached)

I appreciate any input ..

Thanks in advance

NAME
nrsdrv - KISS to NET/ROM serial converter SYNOPSIS
nrsdrv [-f] [-l] [-s speed] [-v] kissdev nrsdev DESCRIPTION
Nrsdrv is a program designed to convert from the KISS protocol to the NET/ROM serial protocol used by real NET/ROM's and TheNet's. The pro- tocols are fairly similar, although the NET/ROM serial protocol does include a one byte checksum which KISS does not. Typically nrsdrv will be attached to one end of a pseudo-tty of which the other end has been attached to a KISS capable program. The NET/ROM device will probably be a real serial port attached to a TNC or a Hexipus. The full specification of the NET/ROM serial protocol can be found in the original Software 2000 documentation that accompanied NET/ROMs. OPTIONS
-f Flow control enabled for use with a Hexipus, the default is disabled. See the file hexipus.txt in the source distribution for wiring details. -l Log messages to the system log, the default is not to. -s speed Sets the speed of both interfaces. If no value is specified then no speed will be set. -v Display the version. BUGS
