thanks everybady about all repons firstly.

i got connection to my new p5 server through my ascII terminal. the
serial port i am using is S1, here i must thank steven_nospam's post.
the terminal setting is 19200/N/8/1 which is mentioned by vlad.

here is a point if somebody is trying to use terminal to connect p5
server. you should change the host/printer to EIA/AUX. and everytime
you need restart the terminal after changing the speed or terminal's
configuration.

Thanks,

frank
