Kind of reverse engineering

Hi everyone,
I'm a linux novice , in a training purpose i have to reconstruct under windows an application running under fedora 14, the application communicates with an STB device through RS232 in a first time and then through ethernet for firmware loading purpose.
All what i know is how to run the application then it shows some informations as "plug the RS232 connecter, restart the STB... " then if done it proceed to send files through RS232 then it reboot the device then it loads other files through ethernet
What i need is to interpret how it communicates with the device, what commands it sends to the device and what it recieves so i can develop my own application in windows, a sort of reverse engineering.

Can you guys help me please?

bpqparms

BPQPARMS(8)						   Linux System Managers Manual 					       BPQPARMS(8)

NAME

       bpqparms - Configure BPQ ethernet devices.

SYNOPSIS

       bpqparms device [-a ethaddr] [-d ethaddr] [-vV]

DESCRIPTION

       Bpqparms  allows  the  setting  of  the	BPQ  Ethernet  options for a particular device. Each BPQ Ethernet device appears as a device named
       bpq0...bpqN which overlays the original Ethernet device, usually eth0...ethN. This device is an AX.25 device driver and allows AX.25 frames
       to be transmitted over an Ethernet to another machine using the same protocol. The default for the device is to send and receive BPQ Ether-
       net packets to the broadcast address. This program replaces the previous "axparms -dev" option.

OPTIONS

       -a ethaddr     Allows the setting of which ethernet address will be accepted by the BPQ Ethernet device.

       -d ethaddr     If specified on its own, will set the destination ethernet address will be used for transmitting and for	receiving  of  BPQ
		      ethernet packets. An address of "broadcast" sets it to the ethernet broadcast address.

       -v	      Displays the version number.

       -V	      The original version messages.
