[Ftdi-usb-sio-devel] Long delay between break signal and first data bytes

[Peter K. <pet...@we...>]

Hi,
I am using an FTDI device on a linux system (2.6.24-21) USB Data are:

FTDZIG54, TTL232R

I am having some trouble to get tcsendbreak() working. I am expecting a 
break level for some milliseconds on the TX line followed by the data.

The C code looks as follows:
//
int sync=0x55;

tcsendbreak(handle,0)
write(handle,&sync,1)
...
//
When I connect a scope to the tx line I can see something like:

~~~~.__,~~~~~~~~~~~~,_|||||
     A break signal
         some 500ms delay
                     the data beeing sent

I wonder how I would be able to send a break, immediately followed by my 
data. The problem is that other devices on the line do not expect such a 
long delay following the break signal.

Any help regarding breaks and general serial programming for ftdi 
devices under linux would be very much appreciated.
I have scaned the internet for some help but nothing apropriate was found

regards, Peter
