I get about +/-10 out of the MAX232Ns from TI, but I use 10 uF/25v
caps instead of 1uF on them (just have more of them in my hellbox).
There are also the cap-less models from Maxim (can't recall the part
numbers) that are pretty tempting.
Some modern equipment gives you +5/0 for "RS232" levels. My DTV set-
top-box with a DE9 on the rear panel labeld "RS232" is such an
example.
Although, I suppose we're going to have to start calling it "TIA-
232".
