command line, any commands to auto-answer or dial must be included in the
AT string.
There are two methods for dialing numbers. The first method uses the format
XFER
/MD#x
, where
x
is a number from 0 through 9. This number
corresponds to a directory number from the modem-initialization file, which
identifies a number that should be dialed for this transfer (see the
NUMBER#
keyword on
). If a number is not specified, directory number
0
is
used.
The second dialing method is to use the
XFER
/MDstr
format, where
str
is
a dialing command to be sent directly to the modem. This string can be any
recognizable phone number text, such as
(555)
444
-
3333
or
5554443333
.
The last
M
option on the command line or in the environment variable is the
one used for controlling the modem. All earlier modem-command settings are
ignored.
If the
M
option is used without specifying a command, the modem will be
disabled for that transfer session. This is useful in the case where modem
commands are specified in the
XFER_ARGS
environment variable (refer to
) but are transferring files without a modem for the current transfer
session.
N
Ignore Previous Option Settings:
This option causes XFER to ignore
previously specified options and return to a default state. All options specified
in the
XFER_ARGS
parameter and on the command line preceding the
N
are
ignored. All options that XFER supports are returned to the default state, and
all filenames, response files, modem-initialization files, and modem commands
that are specified before the
N
(including the
XFER_ARGS
environment
variable) are discarded.
The
N
option is useful when the
XFER_ARGS
environment variable is used to
redefine defaults for XFER. It isn’t always obvious that the
XFER_ARGS
parameter is controlling the behavior of XFER, and it is often the case that
several parameters have been redefined. Instead of having to set each option
back to its default, use the
N
option to return XFER to a known state.
O#
Overwrite Existing File(s):
The
O
option specifies what action the receiver
should take if the file being transferred already exists on the receiver’s side.
When using this option, replace the
#
symbol with the desired setting:
