I followed Rainer's advice and got CL-HTTP running on our 9500 by removing the TCP/IP component of OpenTransport and installing MacTCP. Thanks Rainer. CL-HTTP works fine from a remote host and seems to run pretty fast. Note that we had tried *all* versions of OpenTransport upto 1.1b5 and the MCL mactcp.lisp interface was not working. No incoming connections were picked up by the listening streams.
