Ok, here's more details:
I first used kernel 2.2.13 but then I tried upgrading to 2.2.14-pre14, with
both I can't see my SH888 while I see some friends' SH888. I don't use any
other patches
1. Using RS232 Cable with IrDA:
irmanager -d 1
irattach /dev/ttyS0
insmod ircomm
insmod ircomm_tty
then I can see the modem with irdadump:
14:12:42.917941 xid:rsp 17ccc80e < 59d9f876 S=6 s=2 SH 888 hint=9104 [ PnP
Modem IrCOMM ] (31)
I can use it without any problem using minicom on device /dev/ircomm0
(char major 60, minor 64).
2. Using IrDA on IR port (BIOS setup using IrDA protocol)
irmanager -d 1
irattach /dev/ttyS1
insmod ircomm
insmod ircomm_tty
Then I can see SH888 of a friend, but not mine.
I can also ping my SH888 by first sending a "irdaping 0x0" and then I
get a reply from my SH888.
halley:~/bin # irdaping 0x0
IrDA ping (0x00000000): 32 bytes
32 bytes from 0x3d51bf55: irda_seq=0 time=117.29 ms.
Then:
halley:~/bin # irdaping 0x3d51bf55
IrDA ping (0x3d51bf55): 32 bytes
32 bytes from 0x3d51bf55: irda_seq=0 time=114.31 ms.
When pinging I can see this message in the syslogs:
Dec 18 15:19:07 halley kernel: irlap_driver_rcv(), TEST_FRAME
Dec 18 15:19:07 halley kernel: irlap_recv_test_frame()
Dec 18 15:19:07 halley kernel: irlap_state_ndm() not implemented!
So IR seems to work, but I can't see IrLMP discovery message from it.
If I try to use minicom, then I get no reply from the SH888, and the
last message in the log is:
Dec 18 15:19:58 halley kernel: ircomm_open_instance():
Dec 18 15:19:58 halley kernel: ircomm_next_state: NEXT STATE=0(IDLE),

Dec 18 15:19:58 halley kernel: irias_add_octseq_attrib_R6fc33859()
Dec 18 15:19:58 halley kernel: irias_add_octseq_attrib_R6fc33859: name=Parameters

Dec 18 15:19:58 halley kernel: ircomm_next_state: NEXT STATE=1(DISCOVERY_WAIT),
servicetype=(4)
Dec 18 15:19:58 halley kernel: irvtd_set_termios:
But there are no communications between computer and the modem.
You know, this is really weird... Because the SH888 works under winblows. So
it should not be defect...
I also thought there was maybe several model of this phone. But I asked a
friend who has exactly the same model number and it works for him under
linux.
I hate this kind of problem when you can't identify the source of the
problem... :-)
Do you know a program that can just say if there is IR activity ? Kind
of "raw" measure of IR on the diode ? That could help to see if the modem
sends IrLMP packets or not.
Thanks for your help,
Regards
