This is a rather convoluted question, and for that I apologize. I wrote a Linux C sockets application, a basic framework for a simplistic chat server. The server is running on my laptop. The client is Telnet at the moment until I write a designated client application (that'll be more secure, hopefully). There are better applications for sending generic network data from a client end, I know, but I got interested about why a certain thing happens on one Telnet client but not another.
The first Telnet client test was on another Linux laptop. It works as expected. The next, however, was a Blackberry app called BBSSH that allows Telnet and SSH connections. I went via the Telnet option, and it works too. Except, it doesn't exactly.
The server code does the usual read call to retrieve a block of data, which gets treated as a string, i.e. a message. The former client reads until I hit enter, and then it sends one string of characters. The BB app, however, sends every single character as if I've been pressing enter after each of them, which I haven't. Obviously this is something to do with buffering, what certain clients class as a EOL from the user input, etc. I just can't pinpoint it.
To illustrate, here is the server outputting messages it's received from the clients.
First, the message from the Linux client:
client name: this is a test
Now, for BBSSH:
client name: t
client name: h
client name: i
client name: s
client name:
client name: i
client name: s
client name:
client name: a
client name:
client name: t
client name: e
client name: s
client name: t
Any help?
