Cannot receive data #117

Hello,
For the last two days I am unable to solve this problem:

I tried to run your Qespta example that comes with the download. Eveything went 
fine ( I am using Qt Creator 2.2.1 32 bit, Windows Vista. compiled, library and 
dll produced) first. 
When I run the Qespta project, the transmit works. The port opened (I am using 
a usb-serial converter as i do not have the serial port in my laptop). i have 
checked with serial port monitor program. When I transmit, it seems it also 
works as the monitor program shows that the data is being written to the serial 
port. 

BUT !!!!!!!!!
when I use another instance of Qespta in another computer which has got a 
serial port and from there try to send some data, I get always in my computer 
bytesavailable() is zero bytes received.
I have tried also using eventdriven mode. But the readyread signal never emits. 

please help!!!!!!

thanks,
roy
