Hello all, I have no good idea where to start, so I opted for this list (after google and yahoo). Please CC me on any replies, as I'm not on the list.
I use a PCI card with 4 serial (and 1 parallel) ports, namely an EXSYS 16950/954 card. The card is recognized by the kernel, the ports (and whatever I hook onto the cables) can be accessed ok --- at first sight. I hook an embedded system's console to one of the cards ports, and run minicom (or a script) to access the port. The embedded system will react and give me a shell prompt. After some time (minutes, but irregular) the following symptoms appear: The screen is scrolling, listing text like ATZ: command not found or similar. Interestingly, if I had "date" as the last command, say, the command seems to be rerun (the time changes). I also see commands spawning processes being rerun resulting in several new processes. It seems to me as if the I/O-buffer on the card (128byte) is being sent to the embedded system repeatedly. I have moved the card from an i386 box to a powerpc box (excluding ACPI as the culprit), I have exchanged minicom with a perl script, but the problem persists. The problem goes away if I use the builtin serial port. It could be a silly config problem, but I have no clue where to look for what. Any pointers are well appreciated! Thanks in advance! Erich PS I'm running Debian Linux, 2.6.6 or 2.4.26 kernels on the ``host'' side and uClinux on the embedded side. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
