[Gumstix-users] disable btuart flow ? + btuart strange behavior

[kris d. <t_...@ya...>]

Hi,

I'm currently working on a project to control a DCE
via rs232.  I use the verdex-bt with console-vx.  I
need to use the DTR line, since there is no DTR on the
gumstix, I have to patch something.  So on the
console-vx I plugged the ldd0 (as gpio) to the bt_cts
(to convert the signal to rs232 level).  I also
changed the direction of the bt_ctr signal (gpio45) to
put it as input.

Now, I experiment an extremely strange behavior on the
system.  When I probe the tx line with my scope, I can
see the system keeps transmitting indefinitely (I only
transmit 2 bytes).  If I disconnect the DCE and starts
my software, I can see only 1 transmission.  

Any advice or hint ?

Thank you a lot!
