Modem won't connect at full speed

This has been answered by somebody on some forum, but I lost it.
I have an internal hardware modem. I have configured ppp on demand.
Unfortunately, my 56k modem connects at an effective rate of about
14.4k when I use ppp under FreeBSD. I have got normal connect speeds
with the same modem and the same ISP using Linux in the past.
Here is my ppp.log. Notice the CCP rejection line, which I
guess is pertinent:

# This file is separated into sections. Each section is named with
# a label starting in column 0 and followed directly by a ``:''. The
# section continues until the next label. Blank lines and characters
# after a ``#'' are ignored (a literal ``#'' must be escaped with a ``\''
# or quoted with ""). All commands inside sections that do not begin
# with ``!'' (e.g., ``!include'') *must* be indented by at least one
# space or tab or they will not be recognized!
#
# Lines beginning with "!include" will ``include'' another file. You
# may want to ``!include ~/.ppp.conf'' for backwards compatibility.
#
# Default setup. Always executed when PPP is invoked.
# This section is *not* pre-loaded by the ``load'' or ``dial'' commands.
#
# This is the best place to specify your modem device, its DTR rate,
# your dial script and any logging specification. Logging specs should
# be done first so that the results of subsequent commands are logged.

# Client side PPP
#
# Although the PPP protocol is a peer to peer protocol, we normally
# consider the side that initiates the connection as the client and
# the side that receives the connection as the server. Authentication
# is required by the server either using a unix-style login procedure
# or by demanding PAP or CHAP authentication from the client.
#
# An on demand example where we have dynamic IP addresses and wish to
# use a unix-style login script:
#
# If the peer assigns us an arbitrary IP (most ISPs do this) and we
# can't predict what their IP will be either, take a wild guess at
# some IPs that you can't currently route to. Ppp can change this
# when the link comes up.
#
# The /0 bit in "set ifaddr" says that we insist on 0 bits of the
# specified IP actually being correct, therefore, the other side can assign
# any IP number.
#
# The fourth arg to "set ifaddr" makes us send "0.0.0.0" as our requested
# IP number, forcing the peer to make the decision. This is necessary
# when negotiating with some (broken) ppp implementations.
#
# This entry also works with static IP numbers or when not in -auto mode.
# The ``add'' line adds a `sticky' default route that will be updated if
# and when any of the IP numbers are changed in IPCP negotiations.
# The "set ifaddr" is required in -auto mode only.
# It's better to put the ``add'' line in ppp.linkup when not in -auto mode.
#
# Finally, the ``enable dns'' line tells ppp to ask the peer for the
# nameserver addresses that should be used. This isn't always supported
# by the other side, but if it is, ppp will update /etc/resolv.conf with
# the correct nameserver values at connection time.
#
# The login script shown says that you're expecting ``ogin:''. If you
# don't receive that, send a ``\n'' and expect ``ogin:'' again. When
# it's received, send ``ppp'', expect ``word:'' then send ``ppp''.
# You *MUST* customise this login script according to your local
# requirements.

# If you want to use PAP or CHAP instead of using a unix-style login
# procedure, do the following. Note, the peer suggests whether we
# should send PAP or CHAP. By default, we send whatever we're asked for.
#
# You *MUST* customise ``MyName'' and ``MyKey'' below.

My ISP uses RedHat and does not support FreeBSD, but as I have said,
I have connected at the proper speed using Linux with the same modem.
Any help would be appreciated.
