If i understand well what IrDA does, it implements a full MAC protocol plus probably logical device mux within each node. I don't have the time to read the docs and write a full implementation, that's why i was looking at a faster solution. [I don't even have the motivation, since i don't have any other IrDA-compliant stuff around, and my ppp server would be FreeBSD based] cheers luigi -----------------------------+-------------------------------------- Luigi Rizzo | Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it | Universita' di Pisa tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ _____________________________|______________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
