This one got me some months ago -- its been fixed. The problem (as I
understand it) is that the pyramid box is 'too strictly' adhering to the 
written standard WRT the "push" bit. Since your MacTCP application is not
bothering to send the push bit (it really should send it), the pyramid
is not bothering to send the packets up to the application.

This has been fixed in both 5.1 and in a PTF to the 5.0 product. Contact
your support organization for the fix (also known as the ftp fix).
