It is not about 8052 directly, so sory at the begining of the question. But you have a lot of experience, so I think it is the best place where to ask...

I have to talk to the device using rs232 whitch uses software flow control, but in the description it is writen, that it works with X-ON ONLY I can't get any extra information about the device except what I have.

So, the question is -> is it normal thing? Have you ever used it? I could not find any information about such form of flow control. Everyone is speaking about normal x-on x-off.

Thanks in advance!
