terminal IO for CLI devlopment
Hi all,

Am trying to develop CLI kind of program which does a telcom switch configuration [same like cisco IOS cli]. I have to provide a terminal and a prompt to user for that I did following:
Code:
 static struct termios old_term;
 struct termios new_term;

 tcgetattr(STDIN_FILENO, &old_term);
 new_term = old_term;
 new_term.c_lflag &= ~(ICANON | ECHO);
 tcsetattr(STDIN_FILENO, TCSANOW, &new_term);

This giving me a good control prompt where I can enter whole command string and history & tab features are working too..

But the problem is return key seems not working. When I just press enter key the prompt doesn't go to next line it stays on the same line and shows me next prompt.

if I press 4 times enter key .. it looks like
Code:
cli>cli>cli>cli>cli>

why its not entering to new line? please suggest..

Thanks...

aggregate-ios

AGGREGATE-IOS(1)                                              General Commands Manual                                             AGGREGATE-IOS(1)

NAME

       aggregate-ios - optimise a concatenated set of cisco/IOS prefix filters to help make them nice and short.

SYNOPSIS

       aggregate-ios <source_config >optimised_config

DESCRIPTION

       Takes  cisco IOS configuration on stdin, and optimises any prefix filters found using aggregate(1).  Optimised filters are produced on std-
       out.

OPTIONS

       None.

DIAGNOSTICS

       Any diagnostics produced by aggregate(1) are passed through on stderr.

EXAMPLES

       The following configuration fragment:

         ip prefix-list AS65530 description Foo, Inc
         ip prefix-list AS65530 permit 10.1.0.0/16
         ip prefix-list AS65530 permit 10.2.0.0/16
         ip prefix-list AS65530 permit 10.2.1.0/24
         ip prefix-list AS65530 permit 10.3.0.0/16
         ip prefix-list AS65531 description Bar.Com
         ip prefix-list AS65531 seq 5 permit 192.168.1.0/24
         ip prefix-list AS65531 seq 10 permit 192.168.2.0/24
         ip prefix-list AS65531 seq 15 permit 192.168.0.0/19

       is optimised as follows:

         ip prefix-list AS65530 permit 10.1.0.0/16 le 24
         ip prefix-list AS65530 permit 10.2.0.0/15 le 24
         ip prefix-list AS65531 permit 192.168.0.0/19 le 24

BUGS

       All those in aggregate(1) and then some :)
