Cell data to/from UART

Does anybody have a sample app that will make a cell data call and route data between the cell call and a 76xx UART channel? I’m posting this on the MangOH forum, but the chip will be soldered to a custom board - I don’t even know if Legato still applies. This is posted under MangOH Red because that’s what I have for development.

Data volume will normally be light, with rare downloads up to 2 megabytes.
