Re: monitoring /dev/ttyS0

Additionally posting why (ie which error) the Java application could
not open the pty would be necessary to enable anything except wild
guesses. The wild guess would be 'Are you perhaps trying to open a
lone pty-slave?'.

monitoring /dev/ttyS0

glider...@none (gliderman) — Fri, 10 Oct 2008 20:10:27 UT

Hi
I have a modem using the ttyS0 serial port. This port is used by a java
application X. I would like to log the data on /dev/ttyS0 when
everything is running (modem and java application). So I tried interceptty
which is a program that can sit between a serial port and an
application, recording any communications between the application and

Did you mean to connect to a different server with the Java client?
The error below means that the server refused the connection, usually because
there is nothing listening on the requested port.

linux TCP socket program for java client to c server

tsanchung.w...@gmail.com (TsanChung) — Fri, 10 Oct 2008 14:51:43 UT

I want to make a java TCP socket client to communicate with a TCP
server socket on linux.
Are there some sample C unix server and java client socket programs
available?
The Richard Stevens' "Unix network programming" book described a TCP
server (tcpcliserv04.c) and client (tcpcli04.c). I compiled and

This sounds as if you were using stdio-routine to write to this
file. By default stdio-streams 'connected' to regular files are block
buffered, which would match the behaviour you described. Depending on
how you generate the log message, you should probably either
- use the stderr stream, possibly after having redirected

/var/tmp concept clarification

Hi all,
I am running a client server application on UNIX platform.
Every activity with the server is logged to a specific file..
But when i tail the server side logs, i see it updated after a certain
specified amount of time.
What i am assuming is that the write to the Server side log file is
buffered so it is being updated after the buffer is being filledup.

Thanks. I was looking at the source for syslog and crt0 which use the
internal ones, so I didn't see the public version. Obviously that is
preferable.

And Solaris has getexecname. Now googling for the 3 variants leads to a
piece of code in mesa (the graphics library) that defines a macro
GET_PROGRAM_NAME as a wrapper to these.

Please don't use the `internal' _getprogname() and __progname symbols,
but their `public' version: getprogname(). They are defined by stdlib.h
in the BSDs and their manpage states:
HISTORY
These functions first appeared in NetBSD 1.6, and made their way
into FreeBSD 4.4.
For older versions of FreeBSD you can always define a program-specific

The BSDs include a getprogname() and setprogname() pair of functions.

Re: getting main's argv[0]

n...@vulcan.lan (Nate Eldredge) — Thu, 09 Oct 2008 18:51:06 UT

It looks like some flavors of BSD have a function '_getprogname()' and a
variable '__progname'. It seems to be undocumented and could change.
I don't think so. You might be able to unwind the stack by chasing the
frame pointers, but some compiler options might make this impossible.
I presume you're writing a library, so that main() is not your function.
