Hello,
I have Acer Travelmate 4400 and want to print via irda.
I have studied tuxmobil, linuxprinting and so on.
irdadump produces :

11:36:00.724221 xid:cmd 29b6895e > ffffffff S=6 s=0 (14)
11:36:00.812224 xid:cmd 29b6895e > ffffffff S=6 s=1 (14)

11:36:04.252439 xid:cmd 29b6895e > ffffffff S=6 s=* pink hint=0400 [ Computer ] (20)

Which I don't understand but assume irda is working, but cant connect with printer. Printers leds do nothing, while on Windows they blink.

What may be wrong ? Below i put all info that you might ask about.

Bios : i enabled irda port in bios;
Kernel : 2.6.15.1 , isa enabled, irda :
CONFIG_IRDA=m
CONFIG_IRCOMM=m
# CONFIG_IRDA_ULTRA is not set
# CONFIG_IRDA_CACHE_LAST_LSAP is not set
# CONFIG_IRDA_FAST_RR is not set
# CONFIG_IRDA_DEBUG is not set
CONFIG_IRTTY_SIR=m
CONFIG_IRPORT_SIR=m
# CONFIG_USB_IRDA is not set
CONFIG_NSC_FIR=m
CONFIG_WINBOND_FIR=m
# CONFIG_TOSHIBA_FIR is not set
CONFIG_VIA_FIR=m
# CONFIG_BT is not set
CONFIG_IEEE80211=y
CONFIG_IEEE80211_DEBUG=y
CONFIG_IEEE80211_CRYPT_WEP=y
# CONFIG_IEEE80211_CRYPT_CCMP is not set
# CONFIG_IEEE80211_CRYPT_TKIP is not set

dmesg | grep serial
serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A

All i can do now is :
mknod /dev/irlpt0 c 161 16
chmod 666 /dev/ir*
irattach /dev/ttyS1 -s
cat FILE > /dev/irlpt0

and it hangs, nothing is printed. What have i skipped ?
