We have Sunlink X.25 6.0 running on Sun 4/110 with SunOS 4.0.3 on both ends of the link. Once a while when we rlogin to either one of these Sun 4/110, there is no echoing. We use 'stty -a' to check and everything seems normal. Does anybody experience this problem and know how to fix it. Please send me e-mail, thanks. Lap-Yun Yau uunet!smosjc!lapyun
