InputStream keeps reading forever

Question

Hi,
I have a 'little' problem with input stream. I have a Telnet connection established and I'm reading the input I receive. I read some input and then I send commands. I'm reading the input inside a while loop like this one:
InputStream in = telnet.getInputStream();
char ch = '';
while (condition) {
    ch = (char)in.read();
}The problem is that, when the input is over, in doesn't get out of read and it stays there forever. It doesn't event returns -1, the last char read, anything, it simply doesn't gets out of there. Is there a way to know when there's no more input to avoid this from happening? I can't use read(byte[]) because the input varies and I can't know how many data will be received. There's also no indicator of the end of data like: EOF or -1.
I will appreciate any help.

Nope, it's not the condition. And it's not a file what I'm reading, it's the input from a Telnet connection. My condition is:
InputStream in = telnet.getInputStream();
char ch = '';
int chaux = 0;
while (chaux != -1) {
chaux = in.read();
ch = (char)chaux;
}I'm printing the values that chuax and ch are getting, but, when there's no more input, it just stops reading and the loop doesn't continues or breaks.Ah, ok, I missed that part on telnet; the stream obviously didn't hit an end of file condition then so you have to stop reading on another condition such as the end of the line or maybe
the InputStream.available() method can be of any use. Interactive input streams can be messy.
kind regards,
