[M4IF Technotes] Question on MoMuSys FGS Reference Software

[Alisson Vasconcelos de Brito / Pos. COPIN]

Hi all,
	I am also using the Momusys FGS reference software, but the user
manual does not help us how to encode using FGS .par files. I have tried
both encoder as FGS_server, but they didnt work. Can anybody helps me?
	Thanks,
		Alisson Brito.
