- It looks like I have, somehow, created a very strange problem on the Sun
- work station which I administer. I have a PC equipped with "Kermit" Version
- 3.11 connected to this Sun via one of the TTY serial lines. The Sun thinks
- I am a VT-100. Everything works perfectly. Things used to work perfectly
- when I called in via our telephone dial-ups and telnetted from a terminal
- server to the Sun. Recently, when I telnet in through the terminal server,
- I find that the display is wrong when using VI. After capturing the screen
- data from a properly-working serial line session and one of the botched
- telnet sessions, I see that the botched data contain different VT-100 control
- sequences. What is even more strange, A newer model PC with "Kermit" Version
- 3.11 works right every time. I can duplicate this problem 100% of the time
- and it makes no difference whether the PC is connected to the terminal server,
- directly or is connected through a telephone modem. It also makes no
- difference whether the data are being sent at 9600 baud or 1200 baud. This
- rules out hardware glitches caused by line noise or the PC's inability to
- keep up with the data flow.
- The terminal server-PC combination still works perfectly when
- telnetting to a Vax running Ultrix, so I think that there is something
- different going on between the way the VT-100 control sequences are being
- handled when going through the telnet function as opposed to going through
- the serial TTY line. What am I overlooking?
