If a response file is included in the
XFER_ARGS
environment variable (refer to
page 3-26
), the
N
option can be used to ignore the response file and start from a
default condition (refer to
page 3-20
).
Response files can be used with the
S2
option (refer to
page 3-23
). In this case,
the format for the response file would be:
In this case, the first filename on a line specifies the file on the sender’s side.
The second filename on the line specifies the filename the sender will pass to
the receiver.
The
@file
option can be used only in Zmodem transfers. The
Z
option must
be specified before the
@file
option. If a response file is used with the
S2
option, the
S2
option must be specified before the
@file
option.
All other rules governing filenames apply to response files.
#
COM Port:
This option specifies the communications port to use for the file
transfer. Replace the
#
symbol with the desired setting:
1
=
COM1 2
=
COM2
B#
Baud Rate:
This option specifies the baud rate to be used for the file transfer.
Replace the
#
symbol with the desired setting:
2400 4800 9600 19200 38400 57600 115200

Crash Recovery
(Zmodem only)
:
Crash recovery refers to the ability of
Zmodem protocol to detect that a file transfer was not completed and to
attempt to recover at the point of failure (instead of recopying the entire file).
For instance, if the communications link is severed during the transfer of a 10K
file, with only 5K of data successfully transferred, crash recovery can be used to
send the remaining 5K without resending the entire 10K file.
autoexec.bat c:\autoexec.bat
c:\programs\theprog.exe c:\prog.exe
c:\data\file1.dat d:\data1
c:\data\file2.dat d:\data2
c:\data\file3.dat d:\data3
The receiver’s filename is separated from the sender’s filename by a single space. If
more than one space is used, the additional spaces will be included as part of the
receiver’s filename. Because a space character is used as a delimiter, Windows 95 and
Windows NT filenames with spaces as part of the filename will not be parsed correctly
and should not be used. Placing quotes around the filename will not help in this
situation.
