SDLC Link Driver Error Messages
CAUSE: The I frame was never acknowledged, because the frame was
delayed by the network longer than the configured
REPLYTO parameter
on the host system.
ACTION: Check all possible network delays, and increase the REPLYTO
operand of the GROUP macro in the host’s ACF/NCP generation
accordingly.
2010 MESSAGE: PSI detects an internal error.
CAUSE: The PSI is experiencing problems.
ACTION: Write down the error information displayed on the console,
submit an SR, and call your Hewlett-Packard support contact.
CAUSE: The host system is transmitting data before the HP 3000 sends
a final bit in its frame to relinquish control of the line.
ACTION: Run the SNACONTROL STATUS command, and check the Frames
Retransmitted value in the link-level status information (see Chapter
6 , “MPE Commands,” of this manual). If the value is
not zero, ensure
that the REPLYTO operand of the GROUP macro in the IBM host's
ACF/NCP generation is large enough to account for all network delays.
2011 MESSAGE: PSI detects level 1 line loss.
CAUSE: The level 1 connection was severed. The PSI detects this when
Data Set Ready (DSR) or Clear To Send (CTS) is disabled unexpectedly.
ACTION: Ensure that your modem is still on and functional, and that
the cables are connected properly. Also, check with your phone company
to ensure that your line is still active.
2012 MESSAGE: A PSI internal timer popped.
CAUSE: In SDLC, the only PSI internal timer not noted elsewhere is the
Clear To Send (CTS) timer. The CTS timer pops when the modem never
enables CTS in response to the PSI enabling Request To Send (RTS).
ACTION: Ensure that your modem is still on and functional.
2013 MESSAGE: Unknown error while attempting to autodial.
CAUSE: Before attempting to automatically dial, the PSI detected
something wrong. Specifically, the PSI detected an active ACR line
before attempting to automatically dial.
ACTION: Check your automatic dialer and the modem.
2014 MESSAGE: Autodial phone number configured incorrectly.
CAUSE: The configured automatic dial phone number is wrong.
ACTION: Use NMMGR or the configuration file critical summary to
ensure that the Phone Number configured for the link is correct.
