The wiki has the following to say:

Using the second serial port The Chipkit Uno32 PIC32MX320F128H has 2 serial ports. The second serial port is on the extra non-standard pins 39 and 40. 39 RF4 PMA9/U2RX/SDA2/CN17/RF4 <--- RX data IN 40 RF5 PMA8/U2TX/SCL2/CN18/RF5 <--- TX data OUT This is supported in the UNO32 configuration as Serial1. Note The first release of the MPIDE did not have this support in the PIC32 Uno core files. This was added May 25, 2011.

I think those are reversed on my UNO32 board, if the WIKI is wrong I hope this post prevents others debugging for hours like I did :)

Can you provide a link to where this is in the Wiki?

I just checked the Uno32 schematic and cross checked it against the PIC32MX3xx/4xx Family Data Sheet ... Digital pin 39 (connector J5 pin 12, IC5 pin 31) is U2RX and digital pin 40 (connector J5 pin 14, IC5 pin 32) is U2TX. I believe that the information in the wiki is correct.

What leads you to believe that it is incorrect?
