And I also have the same problem. The TCPFTP-Package works well with UNIX-Workstations such as Sun-3, Sony-NEWS, and VAX11. But TCPCHAT-Package can not connect to SunOS4.0(Sun3), NEWSOS3.2(Sony-NEWS) and ULTRIX2.0(VAX), but can connect to SunOS3.5(Sun-3), NEWSOS2.2(Sony-NEWS) and Bridge Communication-Server's port. When I trace TCPCHAT's packet, it seems that the protocol of SunOS3.5 and SunOS4.0 are different. (NEWSOS2.2 and NEWSOS3.2 has same problem.) I think that NEW-UNIX(4.3BSD and like that) uses different TELNET-protocol from OLD-UNIX(4.2BSD and like that) for some reason. TCPCHAT knows only one protocol of OLD-one, so TCPCHAT cannot connect to NEW-UNIXs. I found difference of protocols, but cannot fix this problem. -- Tetsuo Sakaguchi, University of Library and Information Science, JAPAN E-mail address: saka@ulis.ac.jp (JUNET/ULIS) 74420.237@CompuServe.COM (INTERNET/CompuServe) PEC00237 (NIFTY-Serve only)
