When either type of application writes to a socket, the information is instead sent to the console, if one is present, or is discarded. .RS .PP Note that the current escape resp. quoting of arguments for windows works only with executables using CommandLineToArgv, CRT-library or similar, as well as with the windows batch files (excepting the newline, see below). Although it is the common escape algorithm, but, in fact, the way how the executable parses the command-line (resp. splits it into single arguments) is decisive. .PP Unfortunately, there is currently no way to supply newline character within an argument to the batch files (\fB.cmd\fR or \fB.bat\fR) or to the command processor (\fBcmd.exe /c\fR), because this causes truncation of command-line (also the argument chain) on the first newline character. But it works properly with an executable (using CommandLineToArgv, etc). .PP The Tk console text widget does not provide real standard IO capabilities.
