Hi, I had a very bad week-end trying to configure correctly my connection to the internet thru a modem. The problem is that the data transfert is very very slow. Under windoze, everything works fine. But with Linux it is catastrophic :( I've 2 possibilities to enter the net : either by my ISP using PPP or by my company with a callback procedure using CSLIP. Both have the same behaviour : - ping, nslookup, transferring small files seem to work normally. - on the other hand, transferring larger chunks of data is really painful : most of the time the connection get stuck every 4 or 5 seconds. Then it starts again moving a burst of data then it goes stalled, etc. Stopping a transfert, then restarting it improves the situation. Watching the connection with various monitoring tools confirms these symptoms (but does not give an explanation ) : transfert occurs only from time to time, apparently at random. I have checked the data flow control : it seems ok. The modem is configured (by default or explicitely using &K3) to enable hardware flow control. The serial device says (with stty) that crtscts is on. Xon,Xoff is not set (actually I don't know how to enable it properly). I tried to use IRQ 0 (instead of the normal value 4) for the serial port to see if any conflict may cause the problem. But, in this case, I could'nt establish the connection. I'm currently working with linux 2.2.13. I tried a older kernel 2.0.35 but it did't help. The modem is an Olitec Speed Com 2000. Don't know where to dig to fix the problem : the kernel networking package, the serial driver, the modem configuration .... Any help would be welcome ! -- ____________________________________________________________________________ Jean-Paul Le F�vre * CEA Saclay DAPNIA/SEI * Mail : [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to [EMAIL PROTECTED]
