    Thanks to those that replied (all TWO of you - perhaps the rest are just
    waking up after xmas!)

    For those that don't know -

    I'm having trouble getting my system to work properly - the SCC ports in
    particular.

    The system is as follows : Cyrix M11-233 - 32Mb RAM - 520Mb HD - 4 x tty
    ports (on separate irq's) - a BayCom USCC four port card at 0x300h IRQ5 - a
    PacComm PC100 two port card at 0x280h IRQ2(9) - a YAM on ttyS1, KISS TNC's
    on ttyS2 and ttyS3.

    Giving a grand total of: 4 x 9K6 ports, and 5 x 1200bd ports.

    Kernel - 2.2.13
    Latest axtools, utils & libax25.
    dl1bke's version 3 driver (for 2.1.x and up kernels).

    xfbb7, jnos1.11d

    I had a close look at z8530drv.conf and checked it against the docs &
    examples. Nothing looks wrong.

    I re-compiled the scc module with the extra delays as per the documentation.

    The symptoms are :

    scc port goes into tx - until timeout - no data transmitted

    sccstat reports that it's tx-error count matches it's tx count on all ports.

    They all work fine under DOS, so there is something wrong with the timing
    somewhere.

    The motherboard is a PC-Chips TX-Pro-II with o/b sound & video. (sound
    disabled in bios).

    I get no errors, only the one from axip because it can't connect to the
    other end of the link.

    Then there is just one more oddity...

    One of the kiss tnc's only seems to be transmitting EAX25 & DAMA frames, and
    won't respond to normal ax25 connects.

    Has ANYONE got any clues as to where to look next.

    Regards

    Rob G1ZPU
    not @ GB7ZPU since it doesn't work except for it's 4m port!!!!
