	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...
