Subject [NET] Problem in TelnetInputStream
Date Fri, 16 Jan 2004 19:50:38 GMT

I'm using Commons Net 1.1.0 with Java 1.4.2 on Linux RedHat.

I have written a driver to do some RFC2217 communication. All initial 
subnegotiation is ok, and when I send a first command to the distant 
serial port ("ATZ"), I receive the correct answer ("0\r").

But then, everytime a message should come up through the telnet 
connection, I get nothing immediatly. When another message is sent, I 
get the first one. And so on... Or if I write myself something, then the 
message I was waiting for is also unlocked from the socket.

I've tracked down the problem in TelnetInputStream, and it seems that 
the program gets stuck in the method, at the top of 
__read(). I have checked with Ethereal that the message I'm waiting for 
has correctly been transmitted over the network, but this read() method 
keeps blocked.

I didn't find any cause of deadlock anywhere. I'm trying to get a 
lighter program to reproduce the problem.

Does anyone had something similar ? The problem is becoming quite urgent
