一
BIOS下红外接口默认关闭,而linux-2.6.17前没有pnp处理,需要进入BIOS下手动开始或对内核打补丁,详细请参考:
二
在我使用的FC4上已经安装了irda-util,版本为0.9.16-7,然而系统自带的irda启动脚本不能正常启动irda接口,参考网上资料,采用以下启动脚本:
#!/bin/sh
#Start up the IrDA process and load necessary modules
#
case "$1" in
start)
#Start IRDA
echo -n "Starting up the IR modules"
modprobe irda
modprobe ircomm
modprobe ircomm-tty
irattach /dev/ttyS1 -s
echo "Done."
echo ""
;;
stop)
#KILL IRDA
echo -n "Stopping IRDA and removing used modules"
#Kill the irattach process and remove the modules
killall -9 irattach
rmmod ircomm-tty ircomm irda
echo "Done."
echo ""
;;
*)
echo "Usage:irdastart.sh{start|stop}"
echo ""
exit 1
esac
exit 0
保存
chmod 755 myirda
chmod 755 /dev/ircomm0
开启:
./myirda start
关闭:
./myirda stop
测试:
打开手机红外线,对准接收窗口,./myirda start,运行irdadump命令,应该有数据显示,否则红外设置不成功
正常情况下可以看到类似以下信息:
16:59:12.083873 xid:cmd 9044ea60 > ffffffff S=6 s=* localhost hint=4400 [ Computer LAN Access ] (25)
16:59:12.082870 xid:rsp 9044ea60 < 0000277b S=6 s=5 Nokia 6020 hint=b125 [ PnP Modem Fax Telephony IrCOMM IrOBEX ] (27)
三
下载openobex
./configure --enable-apps
make
make install
