- The following messages are appearing in /var/adm/messages on
- one (two?) of our customer's machines.
-
- From the time stamps, it appears as though software controlling
- these ports may be seeing what it thinks is a "Ring Indication"
- (DCD going high) at the same time this occurs.
-
- The messages are:

-
- Unit 0 is the SP/C card (Sun SBus port expander) and the "line" numbers
- are the serial port numbers.
-
- We see only the stc_drainsilo messages at one of the customer sites.
-
- The configuration is:
-
- Sparc1+ clone (CompuAdd) and IPC
- Sbus Port Card, running Version 1.1 with patch 100464_01
- Ports are attached to a TS1000 (NET's StatMux, now called SPX5)
- running at 9600 baud.
-
- The SBus cards attached to modems running at 2400 baud do NOT seem to
- experience the same problems, so could it be that the TS1000 is
- sending garbage to the SP/C card, or the SP/C card can't handle the
- speed of the TS1000? As you can see, these messages are sporadic, as
- we "talk" thru these ports multiple times (10-20) every hour.
-
- I've used the new SunSolve CD to search bugs/patches and common problems,
- as well as looked at the Patch List recently posted. Due to various
- hardware/software vendors involved, we not sure who should be called in.
-
- Any insight, suggestions, (or even fixes???) would be greatly
- appreciated.
