[irda-users] [long] Stil problems with irda

[WiseLYNX <wis...@fa...>]

Some times ago I asked help on this list because I couldn't manage
getting my irda port working. All was resolved when I found at last what
was my chipset, and that I had to setserial the uart to none.

Now... now the irda is up, and I can happily discover other devices (I
tried with my cellular and another laptop running WinXP). But all stops
here.

Mhh? What the problem is? I really don't know. If I run minicom, it does
not matter on which port and with which parameters, it suddenly=20
disconnect the irda device it previously saw, and minicom freezes (I=20
have to kill -11 it, and it badly crashes the terminal from which I=20
launched). This is the "fun" result, seen through irdadump eyes:

One more detail, after all of this happens, I have no way to have the=20
irda to discover again devices but rebooting the machine. Which is, in=20
my opinion, a very bad thing under a GNU/Linux environment.

I found in a web page=20
(http://www.hpl.hp.com/personal/Jean_Tourrilhes/IrDA/IrDA.html) a notice=20
about bugs with Ericsson T39 (my phone :-). I tried to apply the=20
"patches", but I have some difficulties in applying the one in=20
/proc/sys/net/irda/max_tx_window, because I get an error saying the file=20
does not exist. Anyway, it doesn't seem to work, and it seems my irda=20
get blocked before it can reach those problems.
