SEE ALSO

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

Instruct Tcl to read pure bytes from a channel and write bytes to it, rather than characters:
  fconfigure $binaryDataFile -translation binary

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...
