Sounds like what you really want is not simply a gps cape but a cape that implements the GE864 GSM module that happens to do both GPS and GSM cellular. Hopefully you have the GE864-GPS variant as the other versions do not include GPS functionality. Personally I wouldn't use this module as you will likely have some difficulty soldering it to your board without paying good money for an assembly house to fab assembled boards for you. The module is a BGA package and looks to be a somewhat troublesome to use. Ultimately what do you want this cape to do? If all you want/need is GPS I'd highly recommend using a different solution. If you need cellular connectivity AND gps I might still recommend using 2 seperate modules for a cape, each with it's own connector. doing so will mean not having to build hundreds or thousands of boards to keep costs sane. You or I are NOT going to be able to build this cape for less than the 130 euros that Exploitsys is asking for the cape, especially when the module alone is 45-50 euros plus the other parts for the BOM on that board. If you want that board, buy one from Exploitsys.... It'll be your best deal.
as for using RTS & CTS signals on a cape compatible with the beagle bone black your pretty much SOL if you want everything else on the board to still work as the pins that can be muxed to provide those functions appear to already be in use on the beagle bone black for other functions such as video. as for a translator for rxd The conservative approach in me says use one but on the other hand it may just be enough for the Beagle ARM SOC to see it as a high level. still with all the level translation and difficulties of using that module I'd look for another solution or just buy a cape from exploitsys.
