Unfortunately I don't have the programming experience to get around one problem. The Mac serial ports are using RS-232 protocol and the Sony ports are using RS-422 protocol. Is there a way for me to convert my signal thru software? Is there a cheap way for me to convert is thru hardware? Any help or comments would be appreciated. Please reply via mail and I will summarize on the net. dmoss@iugrad2.ucsd.edu pa1006@iugrad2.ucsd.edu
