But they forgot to mention that the RS423 uses +- 5 volts and an RS232 uses +- 12 volts. I have some equipment that was built to RS232 specs and will not work with the NeXTstation. Some of the newer modem's out there will work though, as most of them were not built to RS232 specs. There's more than just a pinout difference between the 2 standards (RS423 - RS232).
