Ymodem Batch Transfer Desk Accessory
Ver 1.0, 10 May 1987
by David B. Chiquelin
Note: This program is released into the public domain, however
portions of it are Copyright 1985 by OSS and CCD.
This is a pretty simple desk accessory, but if you call FoReM ST BBSs
and use Flash to do so, you are missing out on the 'better' file
transfer methods. A very nice one is Ymodem Batch. You simply mark
the files you want to receive, then select Ymodem Batch download, and
the BBS will send them all, and the receiving terminal program will
save them on your disk with the same names as on the BBS. Easy!
But, as I said, Flash (which seems to be the terminal program of choice
for a lot of users) does not support Ymodem Batch. Until now that is!
If you boot your ST with YBATCH.ACC you will see the item Ymodem Batch
has been added to the Desk drop-down menu. First - how to exit the
accessory if you should accidentally select it or just need to get out
of it. Press the Undo key and wait until you hear the bell. You
should also see the message that it is aborting. Whenever you hear the
bell ringing (once/second) press ANY key and the desk accessory will
disappear.
How to use it.
Call your favorite FoReM ST BBS. (I know you must have one, all the
better BBSs use FoReM!) You can use any terminal program that allows
you to select the desk accessory; or, in a pinch you can use the VT-52
accessory to call the BBS. When you are in one of the file sections of
the BBS, type a B to enable Batch file selection. It should tell you
it is enabled. If it tells you otherwise, press it again as it was
already on. Now list the files. You will see one file description at
a time and if you want to D/L it type a B to mark it for batch D/L. If
you don't want to D/L it, press <RETURN> to see the next file. (The N
for next is not required as Next is the default.) When you are ready
to D/L the files selected (1 to xxx files, depending on the system set-
up) get back to the file menu where Ymodem Batch is listed. Tell the
BBS to send them using Ymodem Batch by typing a Y. When the BBS says
it is ready to send, press your RIGHT mouse button to get to the
capture window. Now select the Ymodem Batch desk accessory and sit
back!
The files will be saved with the name as they were on the BBS. They
will be saved to whatever the default drive/directory is. (ie., if you
are running Flash on Hard drive C, within folder FLASH, the files will
be saved in FLASH on drive C. If you are running FLASH from drive A,
the files will be saved on drive A.) If a duplicate file is on the
destination drive it will be replaced by the new file. If you run out
of room on the disk it won't tell you (at least in this version.)
The program runs in medium and high resolutions only and was written in
OSS Personal Pascal.
When all files selected have been received the bell will ring at 1
second intervals until you press ANY key. The desk accessory will
disappear and you will be back 'live' in the capture window of Flash
(if using Flash of course). Press the right mouse button again to get
back to the main window.
The program has been tested at up to 9600 bps using Flash with the
expanded RS-232 buffer. I did not test it using the VT-52 emulator at
9600 bps but feel it would probably lose some data at that speed with
the small RS-232 buffer. If you use a 9600 bps modem (the USRobotics
HST) to call FoReM ST BBSs, you REALLY need ST-TERM from Matt Singer.
The Fmodem batch transfer using it is 25% faster than Ymodem with the
HST.)
How to use with the VT-52 emulator.
Run the VT-52 emulator accessory, set up the RS-232 parameters (baud
rate, etc) and then call the FoReM ST BBS. Mark your files to be
received, and when you get the 'Ready to send' cue, exit the accessory
by pressing Undo. Now select the Ymodem Batch accessory and sit back.
When completed, press ANY key to get back to the desktop and then re-
select the VT-52 accessory.
To abort the transfer at any point, press Undo. If when you are back
in your terminal mode the BBS is not responding, type a <CONTROL X>.
I hope you enjoy this accessory and that it makes your modeming a
little more pleasant.
