sir, after connecting to hyperterminal, the typing letters enters like symbols(font-terminal). & in property setting i unable to set data bits, parity &stop bits in the level of 7-even-1
regards
Are you reporting a bug in the Microsoft Hyperterminal?
"after connecting to hyperterminal"
After connecting what to hypoterminal?!
"the typing letters enters like symbols"
That is almost always a symptom that you have not correctly configured hypoterminal - in particular, the Baud Rate.
If you are attempting to communicate with your own target, it could mean that you have not correctly configured the baud rate, etc, on your target.
"in property setting i unable to set data bits, parity & stop bits"
Hypoterminal is not a Keil product - for support on Hypoterminal, you need to contact your normal PC support channel.
Hypoterminal should certainly allow this - why do you say that you are "unable" to do it?
Remember that you have to Disconnect before hypoterminal will allow you to change settings...
