Tauno Voipio I have max232 level converter attached to the circuit.

It is working fine. I did loop back too.


Martin I will go through all those links you have sent me.
I was just wondering now that even at minimal level my pc
could see
AT90S2313. I was wondering If AT90S2313 sends some bytes
back on its
TXD pin upon start up.

Not until you program the AT90 to do something, it will just sit there
doing nothing, a bit like a car without the driver, with the engine
running

In addition, tne OP might also need to jumper RTS to CTS and DTR to DSR
on the PC side of things. If I recall correctly (perhaps not, as I avoid
using Hyperterminal whenever possible), Hyperterminal defaults to
requiring proper levels on CTS and DSR before it will engage.

See http://www.aggsoft.com/rs232-pinout-cable/pinout-and-signal.htm and
many others for info.
