Subject: Getting incomplete reply from socket

I must be missing something. I'm still fairly new to ruby, so I 
shouldn't be too surprised. My first real ruby 'project' is to script 
telling my wireless router to connect and disconnect the modem. I've 
got that part working, but I wanted to add a feature to poll the log of 
the router until I actually get connected.

I should mention that this router does not strictly follow the http 
spec. In some cases it returns no http header, and when it does, the 
content length is usually wrong. These seem to throw the HTTP library 
for a loop (curl too), so I dropped down to the socket library for my 
work.

When I access the log on the router, here's the type of thing it really 
returns (captured via netcat):
HTTP/1.0 200 OK
Pragma: no-cache
Content-Length: 24
Content-Type: application/octet-stream

2003/10/10 20:25:27  Modem starts to dial up to *70,xxx-xxx-xxxx
2003/10/10 20:25:28  Wait for modem's response.
2003/10/10 20:26:37  Since modem has no response. Hang up!
2003/10/10 20:26:42  Modem starts to dial up to *70,xxx-xxx-xxxx
2003/10/10 20:26:43  Wait for modem's response.
2003/10/10 20:27:12  Modem connection baud rate: 48000
2003/10/10 20:27:12  Modem starts PPP.
2003/10/10 20:27:12  Username and Password : OK
2003/10/10 20:27:16  Modem get IP : yy.yy.yy.yy


Here's the ruby I'm using to call it:
def networkSend(tosend)
  reply = ""
  TCPSocket.open($host, $port) do |aSession|
   aSession.send(tosend, 0)
   reply = aSession.recv(10000)
  end
  return reply
end

This is what I get out of ruby (with a trailing blank line):
HTTP/1.0 200 OK
Pragma: no-cache
Content-Length: 24
Content-Type: application/octet-stream


It seems to be missing the body of the message. Does anyone know why?

This happens both on ruby 1.6.7 and 1.8 on Mac OS X.
