[En-Nut-Discussion] Second RS232 port

[Elan Feingold]

I have the Ethernut 1.3g. I would like to enable a second RS232 port.  
According to the manual, the second UART is available (PD2 & PD3, it  
looks like), but I'd need to convert to line levels. From the  
schematic, it looks like I can route the second UART through the  
level converter, but there doesn't seem to be a way to have 2  
separate RS232 outputs (?)

I was thinking of using a Dallas DS275 or a MAX232, off-board. Sound  
reasonable?

Thanks,
