Hi all ! I'm using a Suse90 on a Fujitsu Siemens E series laptop. It seems the serial port don't work correctly. It is very slowly. I connected this port to the PC serial port with simple null modem cable. 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. In the laptop there is a WinXP too ( while I can't use the serial port ;) but it work correctly. So I think the uart is ok. Have somebody any idea ? There is an another problem. It seems the linux can't use the inner IRDA port. It is possible ? Thank you Saca

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.

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
