ΓòÉΓòÉΓòÉ 1.1. A brief overview of Transos2 ΓòÉΓòÉΓòÉ

Transos2 is a utility program for transferring files between computer.
Transfers may occur in the background.  That means, while you are typing away
at the conclusion of your report, you can be transferring the introduction and
main section to you assistant for proof reading (who is diligently playing Mine
Sweeper).

Transfers can be made at rates as high as the OS/2 limit of 57,600 baud.  At
this speed, a 200k file can be transferred in approximately 1 minute.  Slower
baud rates may be used if distances or line conditions require.

Transos2 can be used as a standard data transfer utility where by two users
must coordinate the sending and receiving of files.  However, transos2 has both
an auto-send and an auto-receive option, allowing users to send files to, or
select files from remote computers without needing to interrupt the remote
user.

Leaving a computer in auto-send mode allows remote users to view a file listing
of the local drive.  From the listing, andy group of files may be requested and
transferred, all without the need for assistance from the host.  For example an
office that shares a large number of pre-designed forms can save disk space by
keeping the forms on one PC.  Putting the one PC in auto-send mode allows the
other users to find and download a form at their convenience.

When in auto-receive mode, a pre-selected directory is accessable by any remote
PC for uploading files.  For example, a directory may be allocated for daily
reports allowing department managers to upload their reports.  They can
initiate their transfer without interrupting your own project.

A limitation of transos2 is that a computer cannot be on auto-receive and
auto-send mode at the same time.


ΓòÉΓòÉΓòÉ 1.2. Sending Files ΓòÉΓòÉΓòÉ

To send files, click on the button labeled Send, or select Transfer | Send from
the menu.  Once the send screen, you must click on the button labeled Select
Files to Transfer.  A screen will come up that displays a list of the files on
your current drive.  You can move through the directories on your drive by
double clicking on the directory that you wish to enter from the right listbox.
When you get to the files that you want to transfer, highlight the files in the
left list box by single clicking on them.  When you change directories, all the
files are un-selected.  If you wish to transfer all of the files in a
directory, click on the button Select All.

When you have the files that you want to transfer selected, click on the OK
button.  Once back on the Send Files screen, you can select Send. A message
will be displayed on the status line that tells the total number of bytes and
files to be transferred.  Once contact has been made with the receiving
computer, the statistics of the transfer will be displayed on the screen
measuring progress.


ΓòÉΓòÉΓòÉ 1.3. Receiving Files ΓòÉΓòÉΓòÉ

To receive files from another computer, you must first select the directory
that you wish the files to be put into.  If it is the first time you are
running TransOS2 in receive mode, a dialog box will be automatically displayed
that requests you to select the directory for receiving.  To change
directories, double click on the name of the directory that you wish to enter.
The path where the files will go is displayed below the box of directories.

Once a directory has been selected, you can click on the Receive button.  This
will place the application in receive mode.  When the comptuer receives contact
from the source PC, it will display the total number of files and bytes for the
transfer, and the transfer will begin.

If the sending PC is in auto send mode, a dialog box will appear, and the files
from the remote PC will be displayed.  From here you can select which files you
want to have transferred from the remote machine.


ΓòÉΓòÉΓòÉ 1.4. Modem commands ΓòÉΓòÉΓòÉ

The modem command screen allows you to control your modem.

Dialing a number:
   Use the dialing pad (or keyboard) to enter the number that you want dialed.
   Click the dial button, and transos2 will attempt to dial the modem.  When
   the modem connects with a remote modem, the status line will have a message
   of CONNECT and perhaps a baud rate.  When it connects, the incoming data
   will be displayed in the box labeled remote on the screen.  To respond to
   the incoming message, use the box labeled local.

Transferring files:
   When you are setup for a transfer, click on the cancel button.  This will
   place you back at the main screen.  From there, proceed with the transfer as
   you normally would.

Hanging up the modem:
   When you are ready to hang up the modem, click on the Hang up button.  This
   will send the command to take the modem off-line.  When the modem has been
   taken off-line, a line will be displayed on the status line that says either
   OK or NO CARRIER.

Note:  Some modems have different commands to dial, initialize, or hangup.  If
       you modem needs different commands, you can enter these commands in the
       entry boxes supplied for them.  The tilda (~) character is used for a
       1/2 second delay.


ΓòÉΓòÉΓòÉ 1.5. Selecting a Port ΓòÉΓòÉΓòÉ

This option allows you to choose which com port to use for file transfer. The
possible com ports are COM1 to COM4.

Highlight the serial port you want from the list of available ports, and then
click the OK button.  If the port you selected is not available or doesn't
exist, you will be asked to choose another port.  Once a valid port is
selected, File Transfer automatically uses it as the default port for future
transfers.


ΓòÉΓòÉΓòÉ 1.6. Changing the port settings ΓòÉΓòÉΓòÉ

 File Transfer allows you to change the port setting for you transfer.  The
available options are:  Baud Rate, Parity, and Time Out.

Baud Rate:
   OS/2 supports baud rates from 300 baud to 57600 baud.

Parity:
   Parity can be set to None, Even or Odd.  The default is none.

Time Out:
   This is the time (in seconds) that File Transfer will wait for contact from
   the other PC.  If the remote PC does not respond in the amount of time, a
   message will appear telling you that it has lost contact with the remote PC.
   When changed, the Time Out setting is saved for future use.

Note:  The Baud Rate and Parity must be the same for both the sending and
       receiving machines.  Failure to do this will result in not being able to
       communicate.


ΓòÉΓòÉΓòÉ 1.7. Transfer protocols ΓòÉΓòÉΓòÉ

The following protocols are currently supported by transos2.exe:

Zmodem
   (128 bytes packets)

Xmodem-1K
   (1024 byte packets)

Xmodem-1K-G
   (1024 byte packets / no acknowledge)

Ymodem
   (1K Batch transfer)

Ymodem-G
   (1K Batch transfer / no acknowledge)

If you would like to use one of these protocols, you must select it from the
protocols screen each time transos2.exe is loaded.  These protocols are not
compatible with Auto-Send mode or Auto-Receive Mode.  To use the auto modes,
you must use the direct data transfer option.


ΓòÉΓòÉΓòÉ 1.8. Security ΓòÉΓòÉΓòÉ

When you are using the Auto-Send mode, there are times when we do not want
people to have access to our private files.  The security feature will allow
the user that is in Auto-Send mode to Lock certain directories.  To do this,
use the mouse and click through the directories in the left listbox. When the
name at the bottom of the screen is the directory that you wish to restrinct
access to, click on the Add-> button.  When another user accesses your files,
this directory will not be visible to them.

Note:  If you secure a subdirectory, all directories within that subdirectory
       are inaccessable to the remote PC as well.


ΓòÉΓòÉΓòÉ 1.9. Auto loading LCOS2 ΓòÉΓòÉΓòÉ

The checkbox that is displayed at the bottom of the main window is for people
who wish to load the application LCOS2.EXE when they start the transos2
program.  LCOS2.EXE is the port selection program for use with the Logical
Connection Device.  If you are transferring through a Logical Connection
device, you must select the other serial port that you wish to transfer with.
Be sure to check the bidirectional box when selecting the other port so that
the information will be correctly returned to your port when the transfer is
done, you must use LCOS2.EXE again to re-select the printer that you were
previously selected to.


ΓòÉΓòÉΓòÉ 1.10. Auto Send Mode ΓòÉΓòÉΓòÉ

If Auto Send mode is selected, the sending PC will allow the receiving PC to
request the files to transfer.  When the files have been chosen, the transfer
will take place just like in standard mode.  After the files have been
transferred, the program automatically sets itself back into send mode, and
awaits another file request.


ΓòÉΓòÉΓòÉ 1.11. Auto Receive Mode ΓòÉΓòÉΓòÉ

When Auto Receive mode is selected, the receiving PC will wait for the sending
machine to start the transfer.  When a file transfer is completed, it
automatically starts the receive process again, and is ready for the next set
of files.
