Misleading Error 692 with RAS if HyperTerminal Owns COM Port (160188)
The information in this article applies to:
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q160188 SYMPTOMS
If you invoke a Dial-Up Networking connection on a COM port that
HyperTerminal already has open, or if you try to open a HyperTerminal
session by dialing through a port already in use by Dial-Up Networking in
Windows NT 4.0, you get uninformative and misleading error messages.
If HyperTerminal already opened an active session on a serial (COM)
port and you attempt to open a Dial-Up Networking (DUN) session on
the same port, you get the following error message in the Windows NT
4.0 graphical interface (GUI):
Error 692: Hardware failure in port or attached device.
If Dial-Up Networking has already opened an active communications session
on a given COM port, when you attempt to open a HyperTerminal session
on that same port you will simply see the word(s):
Disconnected
-or-
No Dialtone
in the HyperTerminal interface.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 4.0. We
are researching this problem and will post new information in the
Microsoft Knowledge Base as it becomes available.
