Is this pin out the same for a Mac or an IBM serial connection wired to the
NIC? I am getting really confused with the different type of connections
available.

RS-232 (+/- 12V) or RS-423 (+/- 5V)
http://www.netbsd.org/Documentation/Hardware/Misc/serial.html#mac
Macintosh (mac68k and macppc ) systems use the RS-422 protocol which has
balanced pairs (positive and negative lines) for transmit and receive. To
connect a balanced RS-422 line to a single-ended RS-232 line, tie the
positive receive data line (RxD+) to signal ground, and leave the positive
transmit data line (TxD+) floating.
