Im trying to communicate with FFUART with standard
windows CE terminal, but this does not working. Since
revision 1.14 of uart/serial.c on debug output is
'Write timeout 1, 1'. Revision 1.13 working correctly.
In retail image this this error does not occurs.

    Please try current uart/serial.c,v 1.15

    You said: "In retail image this this error does not
    occurs.". What does it mean? "Retail image works correctly
    with uart/serial.c,v 1.15", or "Retail image do not work and
    do not display error message"...

    Revision 1.14, 1.15 debug does not work too ('Write timeout
    1, 1'), but retail is OK(1.14, 1.15). When I trying
    communicate with modem, I have got no response on terminal,
    but AT commands are carried out.

    Revision 1.13 retail,debug is OK.

    Reassigned to jfabo: 1.14 and 1.15 are yours, please try to
    solve the problem. Thanks.

    As I have observed in the current cvs image the FFUART is
    not working correctly even using uart/serial.c 1.13
    revision. I am on the 'timeout' problem, but there seems to
    be some other problem too.

    I tested serial port with xstuart driver from EP250 BSP.
    (XST3: serial port)
    Only serial.c rev. 1.13 works ok.
    Version 1.14 & 1.15 doesn't work (retail & debug). When a
    send one character on serial port Write timeout 1, 1' is
    displayed on debug serial port.

    I have som doubts on this comment:
    "Date: 2003-07-29 12:39
    Sender: flegy"

    First: I have found problem in the uart/serial.c DisableIR()
    function, when in some circummstances it could case the UART
    to be turne off. Debugging the image I saw that this
    happened and therefor I don't think that the AT commands or
    anything else could be carried out (this is confirmed in the
    ext.serial too see the comment from disoft)

    Secondly, since 25-06-2003 the modem initialization has been
    removed from its temporary place and using only the terminal
    the modem was not turned on and initialized.

    Anyway after fixing the DisableIR() problem the Writetimeout
    did not go away, so I'm working on it. The external serial
    is now working fine.

    Fixed in CVS uart/serial.c rev.1.17.

    I've looked into uart/serial.c,v 1.17 and I've not found
    real bug fix.

    yes, I know, since 26-06-2003 temporarily turns on modem
    gmodem driver.
