serial communication too fast?

[Marco Martin]

Hi,

I'm writing a program in C# which logs data comming from a com port. the
port is set up 8 bit, no parity, 1 stop bit (n-8-1), @ 38400 baud. I'm
supposed to receive this data and simply display it in a listbox. No
problem there. Once I start iterating through the data to do some
manipulation though, it wont print to my listbox unless I put a break point
in my code. Then I get some data printed. A few seconds later, the same
thing happens, and I put a break point in the code again and more data gets
printed. I'm thinking that the data is comming too fast, but I'm running on
a P4 with 512M ram. It just doesn't make sense.
The data comes in fine if I just take it in and print it (like on
hyperterminal for example).

any ideas?

regards,

marco

serial communication too fast?

have your listbox get refreshed every few seconds
(Listbox.Refres h())
you can use a timer and on the tick event refresh the
listbox.

Re: serial communication too fast?

Found an answer, I actualy put a thread.join(250 ms) and it solved the
problem.
