Telnet Using UNIX Vi Editor May Scroll Improperly

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1
• Microsoft Windows NT Workstation version 3.5
• Microsoft Windows NT Server version 3.5
• Microsoft TCP/IP-32 for Windows for Workgroups, version 3.11
• Microsoft Windows for Workgroups version 3.11

SYMPTOMS

If you open a Telnet session to a UNIX system, set the Terminal type to a Windows NT type such as VT-100, and use the UNIX Vi editor to open a file such as /ETC/TERMCAP, moving the cursor from the bottom of the file with the Vi ^U character (scrolling the file back in half pages) fails after a few times and displays only a part of the file.

Other Vi cursor movement commands may also cause this behavior.

This problem occurs when you are using the Telnet application in in the Accessories group of Windows NT version 3.5 or the Telnet application included in Microsoft TCP/IP-32.

This problem does not occur when you use Windows NT version 3.1 Terminal.

CAUSE

The correct screen scroll data is passed to the Windows NT Telnet session, but it is not refreshed on the screen properly.

WORKAROUND

Scrolling the screen back and forth sometimes presents the section you want to view correctly.

STATUS

Microsoft has confirmed this to be a problem in Windows NT and Windows NT Advanced Server version 3.1 and Windows NT Workstation and Windows NT Server version 3.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
