| Toggle carriage return stripping during ascii type file retrieval. |
Records are denoted by a carriage return/linefeed
ascii type file transfer.
When cr is on (the default), carriage returns are stripped from this sequence to
conform with the UNIX single linefeed record delimiter, if the remote system is a unix system.
Records on non-UNIX remote systems may contain single line feeds; when an ascii type transfer is made, these linefeeds
may be distinguished from a record delimiter only when cr is off.

That can be done by transferring a

Set or unset the filename character translation mechanism.|
This command is useful when connecting to a remote
computer with different file naming conventions.
If no arguments are specified, the filename character translation mechanism is unset.
If arguments are specified, characters in remote filenames are translated during
put issued without a specified remote target filename, characters in
local filenames are translated during
commands issued without a specified local target filename.
Characters in a filename matching a character in
replaced with the corresponding character in
If the characters position in inchars is longer than the length
of outchars, the character is deleted from the file name.
ntrans . _
causes DOTs in a filename to be changed to underscores.

This command is useful when connecting to a remote computer with different file naming conventions or practices.
If no arguments are specified, the filename mapping mechanism is unset.
If arguments are specified, remote filenames are mapped during
put issued without a specified
remote target filename and
local filenames are mapped during
issued without a specified local target filename.
Inpattern is a template for incoming filenames

Variable templating is accomplished by including
$1, $2, …, $9 in inpattern.
\ to prevent this special treatment of the
$ character. All
other characters are treated literally, and are used to
determine the nmap inpattern variable values.
For example, given inpattern
$1.$2 and the remote file name
$1 would have the value "my", and $2 would have the value "data".
The outpattern determines the resulting mapped filename. The sequences $1, $2, ...., $9 are replaced by
any value resulting from the inpattern template. The
