Heya, muruganyuva. Welcome to TSDN!

Are you writing a program to do this? What programming language are you using to write the program?

Are you doing this using shell or batch scripts? What operating system are you designing your interface for?

hi,

in my project i'm sending the data from source to destination with the help of modem.
one modem at the source and other at the destination.

at first i'm initializing the source modem.

"AT E0 V1 X4 N1 &D0 &K0 S0=2"

Then i connects the modem and transfer the data.

while disconnecting i change the data mode of the modem to the command mode (+++ command) and then disconnects
the modem by ATH command.

When i again connects the modem and try to send data, its not connecting properly some times.
If we switch off the destination modem and then try means its connecting properly.

how to solve this problem?
Is there any way to reset the destination modem from the source??
