I have /dev/ttyS0 set to 230400 baud through stty.
I have setserial flagged at spd_vhi (though this isn't neccesary)
My pppd options include '115200' (for some reason 230400 won't work),
'crtscts' and 'bsd_cmp 15,15' i think these are the relevant settings.

the chat log reports that i am connection above 50000 so i'm guessing
the problem is with pppd.

so, any ideas what the problem could be?

btw, does anyone know a reliable way to check modem connection speeds?
I've been judging from ftp transfers, and netscape loadings.

thanks,
sam

(You can check this with "ifconfig ppp0" when you're connected)

The best setting for PPP is 576 (for both).

   Both Slackware and Redhat, out of the box, do NOT optimize the TCP/IP
   window size.  This can make a BIG difference with performance.  For more
   information, check out [URLs in Section 5]:
         RFC 1106 - High Latency WAN links - Section 4.1
         RFC 793 - Transmission Control Protocol

         Redhat5:
      NOTE:  Users that have NOT installed the initscripts-3.67-1.i386.rpm
             patch RPM, the correct line numbers will be 119 and 134.  
             Personally, I recommend that you just install the RPM NOW!

      Edit "/etc/sysconfig/network-scripts/ifup" and around
      lines 134, 136, 141, 149, and 158, find the lines:

         134:    "route add -net ${NETWORK} netmask ${NETMASK} ${DEVICE}"
              and
         136:    "route add -host ${IPADDR} ${DEVICE}"
              and
         141:    "route add default gw ${GATEWAY} metric 1 ${DEVICE}"
              and
         149:    "route add default gw ${GATEWAY} ${DEVICE}"
              and
         158:    "route add default gw $gw ${DEVICE}"

      and change them to:
         134:    "route add -net ${NETWORK} netmask ${NETMASK} window 8192 ${DEVICE}"
              and
         136:    "route add -host ${IPADDR} window 8192 ${DEVICE}"
              and
         141:    "route add default gw ${GATEWAY} window 8192 metric 1 ${DEVICE}"
              and
         149:    "route add default gw ${GATEWAY} window 8192 ${DEVICE}"
              and
         158:    "route add default gw $gw window 8192 ${DEVICE}"
