channel, open, socket

EXAMPLES

Instruct Tcl to always send output to stdout immediately, whether or not it is to a terminal:

 fconfigure stdout -buffering none

An important use is

  fconfigure $binaryDataFile -translation binary

to make sure the file is read as binary data.

Some of the wiki pages talk about the construct

fconfigure $serial_port -mode "$baudRate,$plex,$bits,$polarity"

or some such thing. The -mode flag, used for specifying baud rate, etc. has moved to open now. I don't know how one would change those values on an open descriptor...
