Hallo all!
I detected a very mysterious behaviour with my serial connected 56K modem. If
you do a ftp-download e.g., the datas come at the following way:
5,9 kB -- -- --- -- -- -- -- --
4,4 kB - - - -- - - - -
The speed of the incoming data is always swinging between 5.9kB and 4.4kB.
Why? I didn't have this problem with Kernel 2.2.x (with the same
pppd-versions).
Neverthless, the overallspeed seems to be equal to kernel 2.2.x (about
5.1kB/s) - but not slower; it even could be faster. But I think, the speed
could be much higher, if it wouldn't swing as much.
I'm using pppd 2.4.0b or 2.4.1. My modem (USR Sportster Message +) is
connected with 115200 Baud (56000 tested but doesn't work properly), the
connect to my provider is 50,6kB/s.
My serial hardware is
ttyS00 at 0x03f8 (irq = 4) is a 16550A
on a AMD K6 2 400 with ALI 1541-chipset.
I can't see any errors in messages or with ifconfig.
I tested it with or without firewall - always the same behaviour.
The login-protocoll seems not to bee suspicious:

I tried to switch off all softwarecompression. But it doesn't matter.
Do you have any advice for me?

Andreas Hartmann
