That's a speed problem (1152000 is MIR). You are supposed to select the proper module parameters to get speed changes to MIR/FIR to work properly (check IrDA mailing list messages from Daniele). Another solution is to limit the speed of the stack to 115200 (115k - see my web page for details).
Good luck...
