    When connecting to a PC it is necessary to both invert the logic and convert the voltage levels but when connecting to an embedded TTL device, there's no need for either as it outputs TTL levels with positive logic. You will need level conversion if your microcontroller is powered by +5V but that's far simpler than a MAX232.

    OK! The voice of authority! As long as the polarity of the PIC's hardware uart is right for the SocketLAN, life is good. I DO need level conversion from 5V to 3.3V and will use the SN74LVC2G07 with a pullup to the appropriate power supply on the outputs. Thanks to both of you.
