Question about Readline Library
 

Hi, All.
In my Linux program on a computer with Debian Linux I need to have a
simple command line input. I plan to use remote Windows computer as remote console and use it's Windows telnet for communication. I try to use Linux readline library. It works when I use standard input and output. When I create TCP socket, associate file "dirstream" with it and make redirections:
rl_instream = dirstream;
rl_outstream = dirstream;
the readline outputs my prompt ( ">") to remote telnet console, but I cannot input the command. And I see following warning: "rl_prep_terminal:
cannot get terminal settings."

So, the readline seems to work fine with standard input-output, but somehow goes wrong when I try to use non-standard stream ("dirstream", associated with a socket in my case)

Can anybody give an advise?
Thanks in advance, Alex.
