xon/xoff

[claudio222]

I use Rad studio XE Pro ,and i need to comunicate with a logic analizer thru rs-232 , the analizer accept simple command to emulate a keyboard and send back an answer,for example i send CR and the analizer send back the hexadecimal sequence:
13 45 4e 54 45 52 0d 0a 2a 11 (xoff,E,N,T,E,R,cr,lf,*,xon).
now , when i try to receive this data from the analizer at the first time i find only the 'E' character in buffer,and at the second time i find in buffer "NTER/n/r*".
I use the method in the example StringReceiverBCB , i allegate a screenshot of the timing of the signal,
probably i mistake something .

Hi,roman , thank you for your reply , i've solved my problem.
My problem was the breakPoint placed in a wrong position and when i was checking a receive buffer the process was premature stopped and i can't see the data.
The problem was I!!
