The mail hub is a NeXTstation, and the 2 remote machines are a NeXTstation and a 2.0 030 cube. We have the same problems with lockups on remote->hub transfers...however we are only using the serial ports on the remote machines. ie They poll the hub machine by dialing into an annex and telneting to the machine. What seems to be happening (via debugging at level 99) is that the uucp handshaking is ok, but when the execution of the actual transfer commences I get reack errors which result in attempts to resend, but the errors build up. Now, we are using 9600 baud MNP5 modems all around. Different brands have been tried to no avail. Flow control is off (UUCP should handle everything without any problems) and so is speed conversion (9600 baud connection) NeXT has suggested that it could be related to the serial port bug, does anybody have any ideas or suggestions? btw...I have absolutely no problems with hub->remote transfers... ------------------------------------------------------------------------------ Jeff Kight jkight@umd5.umd.edu Information Services jkight@umd2.bitnet Computer Science Center uunet!umd5.umd.edu!jkight University of Maryland (301) 405-3014
