Hello ! Thanks your help but it seems I forgot say a few word about the default problem. The laptop can't use any device wich I connected to the serial port. I would like use an standard external modem but it can't work (the modem didn't answer). Next I want set the GPRS connection but it didn't work neither. I knew the devices working correctly because I probed them with a PC. So I think maybe the serial port undown. I connected the laptop to the PC with an simple nullmodem cable and try send some string. I saw the communication wery slowly. Here is some information from the laptop : ############################### Interrupts -> /proc/interrupts ############################### CPU0 0: 5314052 XT-PIC timer 1: 2318 XT-PIC keyboard 2: 0 XT-PIC cascade 8: 2 XT-PIC rtc 9: 142475 XT-PIC acpi, ICH, eth0, O2 Micro, Inc.

I send a string out (echo 'Hello' > /dev/ttyS0) from PC and read on Laptop (cat /dev/ttyS0). The communication reading was verry slowly. It was some string which can't arriving to the laptop. I probed change the communication direction but in this case the writeing was very slowly.
hm, try "setserial -bg /dev/ttyS?" to see if your UART ist detected correctly. Then you probably need to setup the serial ports on both machines to sane parameters using setserial or something like that.
I would try a terminal program like "minicom" on both machines or simply
screen /dev/ttyS0 57600 (57600 is the serial speed) on both machines. To quit screen press "CTRL-A k" simply using cat probably leaves the serial ports uninitialized or they are using some settings the BIOS assigned to them, which may not be the same on both machines.
There is an another problem. It seems the linux can't use the inner IRDA port. It is possible ?
Sorry, there are a lot of different possible IRDA setups, so you either have to provide more details or try searching reports for your model on http://linux-laptop.net or http://tuxmobil.org -- Stefan Seyfried

probably your irda port
It seem correctly but these days I discovered an error message in the boot.msg

this is normal

this is only a warning. Do you have a smartlink Softmodem configured?

i don't know about this one, probably setserial which is called from /etc/init.d/setserial has problems with the irda port.

Do you have any idea ?
not really, also i don't know why the slmodem modules are loaded, maybe they interfere with the serial ports, you never know with such binary only things :-) Did you try my suggestion with "screen" on both sides and the nullmodem cable between the machines? Of course you can also try minicom or some other terminal program. The problem may be that "cat" does not set up the serial ports correctly, so it may sometimes work but fail on the next try. -- Stefan Seyfried
