OpenTransport problem on OS9.2.2

Our application uses an OpenTransportSupport CFM library of
our creation. The application is CarbonLib based.
Atop that library is some Lisp code that interfaces to
OpenTransport.
Here is the problem.

(setf stream (open-tcp-stream "www.apple.com" 80))

(progn (telnet-write-line stream "GET / HTTP/1.0")
(telnet-write-line stream "")
(dotimes (x 10) (print (telnet-read-line stream))))

With the above code things work fine on either OS9.2.2 or
on OSX 10.2 or greater if the network connection is a modem
(i.e. slow). However if the network connection is
on a T1 line (through ethernet or airport) or cable modem, it fails
on OS9.2.2 but works on OSX 10.2.
The failure may be garbage returned after about 6000 characters
or sometimes a lisp error or sometimes a crash.

What differences between the OS9 carbonLib implementation
and the OSX implementation might be implicated in this
problem?

I know the info is rather vague, but I'm hoping.
Thanks for any help.
Alice
