I'm working on a project that will be using an Arduino Mega and a Linksprite RS232 Shield https://www.sparkfun.com/products/13029. In the sketch I'm planning on using the SoftwareSerial library. The problem I'm running into is that the SoftwareSerial Library requires an interrupt serviceable pin be used for the Rx line. The shield allows for user selectable Rx and Tx lines within the D0 -D7 range, but the Mega doesn't have an interrupt serviceable pin in that range. My current plan is to modify the shield to allow using a Mega interrupt pin (10 or 11). I just wanted to see if there were any other suggestions to get around the incompatibility?
