Usually the first adapter shows up as /dev/ttyUSB0 If you have multiple you can have issues with which adapter is which name. There's a way to create udev rules so the same name is always bound to the same device.
Power cycles: I suggest getting ups pico board or just always keeping it plugged in to something, could be a battery. As to the board: not really smaller no. The pi already has a serial port it's just at TTL levels instead of rs232. The board I've used is just a max232 chip to do the level conversion. I guess if you built the chip into the cable it could be smaller. Otherwise you're adding a daughter board. I prefer the USB serial devices unless you're out if USB ports. -- John.
