    Connecting WYSE terminals through serial port extensions (Perle board)

    Not exactly familiar with serial port communication--and thats causing a lot of grief...
    unable to get the WYSE dumb terminal working.....I have checked the serial port setting-they seem to be fine...the perle serial port extension (PCI card giving 4 port outlet ) ports show up as ttyPS0-ttyPS3
    Running these commands gives

    setserial -a /dev/ttyPS1
    /dev/ttyPS1, Line 1, UART: Cirrus, Port: 0xe008, IRQ: 2
    Baud_base: 921600, close_delay: 500, divisor: 0
    closing_wait: 30000
    Flags: spd_normal

    setserial -a /dev/ttyS0
    /dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
    Baud_base: 115200, close_delay: 50, divisor: 0
    closing_wait: 3000
    Flags: spd_normal skip_test

    echo /etc/hosts > /dev/ttyPS1
    just waits/hangs on the next line.

    In my (little) experience, i just typed
    w/out quotes
    "getty ttyS0 9600,8,N,1"

    and the terminals worked.

    I realize it's not much help,and I was just using a built in RS-232 port, but thats what I did.
