Irda To Serial Port Switch. Options

[mr_nice]

Hello,
I want to add a switch wich switches between the irda and a new serial port on the irda.
Is it possible to use the irda as rs323?
I dont meen these adapters. I want to solder some cable on the irda and add an switch so I could use my mouse or sth. on that port and if I ever need the irda so is switch between them.
Any pinouts?
thx
