I'm posting this for someone else. Any help would be greatly
appreciated.
I've recommended changing the mtu setting which hasn't helped.
I've also said that the kernel should be re-compiled with ppp support
compiled directly in, not as a module. He says it's not set as a module.
Hi,
I have a Gateway Pentium II PC. I have Windows 95 and Linux on it. I
have
Gateway Telepath X2 internal modem on COM2 and Zoom 56K V.90 external
fax modem on COM1. I am NOT using the Telepath modem. I use Zoom
modem only. My PPP link works great (connects @ 50,000) on Windows 95.
But on Linux it is very very ... slow and stalls every now and then. I
have
RedHat 5.1 Linux.
I have set up ppp0 interface from control-panel. My Zoom external
modem
is on /dev/ttyS0 and uses IRQ 4 exclusively. However both my video card
and
sound card seem to use IRQ 9 (got this info from Windows control panel).
Can this be a problem ? How to assign different IRQ to video card in
Linux ?
My modem init string is ATZ. I tried the init string my from
'mdmzt.inf' The
entries read
HKR, Init, 1,, "AT<cr>" ; do an "AT" to get autobaud correct (start
other init strings with 2)
HKR, Init, 2,, "AT &F E0 &C1 &D2 V1 S0=0\V1<cr>"
I used the Init 2 string also. No difference speed. I tried different
MRU & MTU
values. My /etc/ppp/options file is
/etc/ppp/options

More important even when I execute a cgi-bin script residing
my PC the Netscape
shows 10 bytes/sec transfer speeds and stalls. I suspect that my TCP/IP
configuration is
not optimal.
Any help is greatly appreciated.
Thanks,
