I am attempting to get a Hayes Interbridge working properly with a kbox (KFPS-2) running KIP 01/88. However, I can get everything to work properly under KIP 09/87. Here is a description: When hooking a Mac to the network with the Kbox, I get the zone list sometimes appearing, and sometimes not appearing under chooser. Repeatedly opening and closing the chooser results in zones being recognized about 1/3 of the time. When attempting to look for servers or printers, I sometimes get a response from a server, but many times no response at all. All network services were equally bad in response. When hooking the Mac onto the other net, (with the interbridge appropriately configured), I never get a zone list under chooser. I made sure to aviod having running machines up when configuring the network numbers, and that the kbox and Interbridge absolutely agreed on the same appletalk network number. The problem seems to be more of a KIP <-> Interbridge software problem. (We have multiple InterBridges, Kboxes, and connectors, and have ruled out hardware problems.) Anyone gotten it to work successfully? Any ideas/suggestions? Rakesh Patel.

KIP 01/88's zip query handling is messed up. My fault: this got
introducted when the code was made to handle long and short ddp in
zipinput. The patch follows.
The patch also fixes another minor problem where the count returned
might have been incorrect. It has been tested against Kinetic's
ethertalk gateway and Pacer's VMS gateway. (By the way, Pacer does
the same thing as AlisaTalk -- it setups a an AppleTalk Bridge to
front end the VMS system).
