The IrDA stuff has the master broadcasting before the > slaves will respond. There is a protocol that needs to happen... For SIR, it just transmits what you send it. It's a plain old serial stream. There are layers on top of this (IrCOMM, etc.) but I'm not using them. The problem was apparently an I/O port conflict. I thought I could just disable the serial port and set the IrDA to the same (0x3f8, IRQ4). No go. Once I set it to 0x3e8, IRQ4, it started working. I'm syncing my pilot right now. -- Christopher Masto Senior Network Monkey NetMonger Communications chris@netmonger.net info@netmonger.net http://www.netmonger.net Free yourself, free your machine, free the daemon -- http://www.freebsd.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
