This somewhat depends on the drivers/receivers used.
The 26LS3x ones
generally will work as you want them to. To do the job properly, I'd use
similar chips to convert the signals back to TTL, then add a MAX232 or
similar.
As an alternative to consider, Analog Devices makes a nifty little chip
that's got 422 and 232 drivers and receivers on it, and is +5
powered--AD7306.
