Remote serial port configuration.

Remote serial port configuration.

Hi all,

I have connected two pc's through serial port. And one of the pc is 
configured to run a terminal on the serial port( ttyS0 ) by configuring 
the getty to run on serial port. 

I have written a program to send the username & password from the other 
computer. The configuration of serial port on both the systems are same.

But I am not able to login to the system. But when I give a delay 1/100 th 
of a second or more between sending of username & password, then it is 
getting logging into the system.

Can I log in without introducing any delays?

Pls help me in this regard.

Thanks & regards
vijay kalkoti

Sounds a bit like

	- Handshake wires are missing (so some data is lost)
	- UART type is configured wrongly

May be the following helps:

Current getty programs do clear their input buffer before they issue the
"Password:" prompt.
