TTIME Version 2.0 User Documentation CHAPTER ONE: About TTIME in general... TTIME is a telecommunications utility for the following systems: - Any PC-DOS or MS-DOS compatible system using DOS Version 3.1 or later; - 256K or more of RAM (you'll especially need more if you run TTIME from a shell in your telecommunications program); - Any disk system (hard or floppy) TTIME estimates the needed time to transfer a file from one computer to another, supporting a wide range of modem speeds and a number of the most popular file transfer protocols. If you're not sure what a file transfer protocol is, check the IBM New User's forum on CompuServe, they have some nice descriptions on the various file transfer protocols available. In addition to estimating the required time, TTIME can be configured to estimate how much a file transfer will COST you (be it telephone long-distance charges, connect fees, surcharges, or any combination of the above) as well. TTIME is designed to be easy to use and actually requires very little learning on your part. If you're one of those people who hates reading software manuals, go ahead and quit reading now. Just type the command: TTIME and press Enter. TTIME will take your hand and lead you through the rest. If, however, you want to learn how to make TTIME do all it can for you, keep reading. I promise by the time you're done with this manual, you'll fully understand how to make it work for you, and how you can customize the cost reporting feature of TTIME. WHAT TTIME CAN DO FOR YOU: TTIME will provide it's best-guess estimates for modem speeds of 1200, 2400 and 9600 bps (bits per second, sometimes erroneously called 'baud'). TTIME currently supports the XMODEM, YMODEM, ZMODEM and CompuServe B+ file transfer protocols. TTIME can make its estimates by you giving it the file name you want an estimate for (provided the file is on your computer, and you're sending it to another computer), or by file size in bytes (this method will work for a file you're sending to another computer, but is probably best used to estimate how long it'll take for a file to be sent from another computer to yours). Sept 1, 1991 Page 1 TTIME Version 2.0 User Documentation TTIME can be run as a stand-alone program (from the DOS prompt), but it works best when used as an add-in to your telecommunication program. Many of the most popular telecommunications (or terminal) programs support what is called a 'DOS Shell' or 'Shell to DOS' function where the terminal will temporarily let you run a DOS command, then return to being connected to the other computer system. This is probably the best use for TTIME. More advanced terminal software will actually let you install TTIME using a 'hotkey' (key combination that will run TTIME) so it's always just a keypress or two away. I'll try to help you figure out how to make TTIME work with your terminal software, but you must keep in mind that I can't afford to buy every possible software package and therefore have direct experience with only a few programs. You'll need to refer to the instructions that came with your terminal software in order to learn how to install it on YOUR system and make it work. WHAT TTIME CANNOT DO FOR YOU: It won't actually send or receive programs over your modem. That's what your terminal software is for. It won't be able to predict EXACTLY how long a file transfer will take. TTIME assumes a good phone connection, and bases its estimates on a file being transferred at a normal rate of efficiency (no retries or errors caused by noisy phone lines). If you often have problems with sending or receiving files, then TTIME will probably be incorrect in its estimates of how long a file transfer will take. It won't support any of the new compression tricks that some modems use (such as MNP-4 or MNP-5 data compression). Since the results of these compression techniques depend as much on how good a connection you have as well as the speeds of the modems involved, trying to calculate these figures would give such a wide spread of time from best case to worst case that the resulting estimates would be of no use. It won't support any of the proprietary (private) modem-to-modem protocols (such as the Hayes protocol or the Courier HST protocol), again because of the variable results that these protocols would cause. Sept 1, 1991 Page 2 TTIME Version 2.0 User Documentation CHAPTER TWO: Using TTIME, With Examples: USING TTIME IN THE PROMPTED MODE: Probably the easiest way to start TTIME is to use your terminal software's 'Shell to DOS' command. When the DOS prompt appears, simply type the command: TTIME and press Enter. This will start TTIME in the 'prompted mode', where it will give you a lot of hand-holding and instruct you to either enter the name of the file to estimate the transfer time for, or the file size in bytes. Here we need to get technical for a few minutes - but only for a few minutes, I promise. If you're an experienced DOS jockey and understand such things as 'pathnames' then you'll only need to glance lightly over this section. When TTIME asks you for a filename to provide an estimate for, you have to remember a few things. First, the file must exist on your disk already. This is because TTIME is going to take a look at it to see how large it is, so it can estimate how long the file transfer is going to take. (In the following examples, I'm using all capital letters so the names I'm using stand out. You don't need to capitalize the names when you type them in for TTIME. It understands lower case letters just fine. Also, where you see this symbol: <enter> , this doesn't mean to type the word enter between the brackets, just press the Enter or Return key on your keyboard.) Let's suppose you want to send a file called 'WORKFILE.TXT' to someone else's computer. As long as it's on the disk you're using right now, and in your current directory, this is OK. Just tell TTIME to give you an estimate for: WORKFILE.TXT <enter> But, suppose it was somewhere else? Then, you'd need to add a 'path' to the name so TTIME could find the file. Let's suppose that you start up your terminal software by typing: CD\TERMINAL <enter> PHONE <enter> Your 'current directory' is the TERMINAL directory. Let's say that your WORKFILE.TXT file is located in the WORDSTUF directory. So, to tell TTIME you want to use that file for an estimate, you'd answer: Sept 1, 1991 Page 3 TTIME Version 2.0 User Documentation \WORDSTUF\WORKFILE.TXT <enter> to tell TTIME that the file is on this disk, in the WORDSTUF directory. Even worse, let's suppose it's on a different disk. You're on the C: drive, in the TERMINAL directory, and the file you want to send to the other system is on the D: drive, in the WORDSTUF directory. You'd have to add the drive letter to the name, like: D:\WORDSTUF\WORKFILE.TXT <enter> so that TTIME could find it easily. Supposing that the file is on the OTHER computer? You type in the name of the file, and TTIME tells you 'Cannot find requested file. Press any key..." and nothing happens! This means that the file can't be found on your disk. Of course not! It's on the other end of the phone line! So, you'll have to tell TTIME how large the file is. Usually, when you get a list of files from another computer on your terminal software, it'll include a file size, often somewhere very near the name. Let's say this is a part of a list the other computer has shown you when you asked it to list files: ********************************************************************** * 2 - IBM Utilities ********************************************************************** TTIME.ARC 04-15-91 102453 Estimate file transfer times by phone MASTER.ZIP 04-14-91 91236 Master database program version 3 CLSC.COM 04-13-91 1075 Clear Screen with Colors (more files listed) and you decide to download TTIME.ARC (wise decision! <g>). Since TTIME.ARC doesn't exist on your drive, you'll need to tell TTIME the file size. Looking at the listing, you decide that 102453 must be the file size, right? So, after TTIME asks you for the file name or size to estimate, just answer: 102453 <enter> To summarize, when using TTIME in the 'prompted mode', you'd type in the program name (TTIME), then when it asks you for the file name or file size you simply answer with the name (if the file is on your disk) or the file size (this will work whether the file is on your disk or not, but is most useful when you're having a file sent to your computer). Here are a couple actual examples, using the 'prompted mode' of operation: Sept 1, 1991 Page 4 TTIME Version 2.0 User Documentation (Example One: Prompted Mode, by File Name) C>ttime TTIME Version 2.0 Copyright (c) 1991 by RGH Software Unregistered Evaluation Copy - Did you FORGET to register?

TTIME'S HELP MODE: Should you ever lose your documentation, or forget how TTIME works, simply type the following: TTIME /H <enter> - or - TTIME /? <enter> and TTIME will show you a little help screen to remind you how it works. Sept 1, 1991 Page 6 TTIME Version 2.0 User Documentation INSTALLING TTIME WITH YOUR TERMINAL PACKAGE: This is where my detailed instructions begin to falter. You see, there are literally dozens of popular terminal software packages out there, and each of them has their own little idiosyncracies on how (and even IF) they'll allow you to use external programs (programs outside of the terminal package). Here, I can only offer some very general guidelines on how you might be able to use TTIME with your software package. I've listed them in order of most preferable to least preferable. You should refer to the documentation that came with your terminal package to see which of these methods it will support. If you are in doubt, go ahead and try each method in the order listed. This trial and error approach shouldn't damage anything (but don't blame me if it does!) and you may find a way that works well for you. I would request that you let me know (either when you register your TTIME program, or by CompuServe Mail otherwise) how you got it to work with your terminal software. As I get hints and tips from users on how they got it to work, I'll continue to update this section with the solutions I get. So far, only a few users have told me how they got it to work. GENERAL SUGGESTION #1 - If your terminal package supports the addition of external programs by using a 'hot key' (you press a key combination to call the program) this would be the best approach. GENERAL SUGGESTION #2 - If your terminal package allows you to define an external program such as a text editor, you might want to consider using this approach. This, of course, will mean that you won't be able to use a text editor while using your terminal package. Among the software packages I've recieved tips on that support this option are: Crosstalk-XVI, Mirror and Mirror II. GENERAL SUGGESTION #3 - Some terminal packages will let you install an 'external file transfer protocol' (that is, a program to send and receive files by a means that your software doesn't ordinarily support). You can add TTIME to your list of 'external protocols' and see if this works. Although I haven't heard of a case where this DOES work, I have been told that Telix will let you define TTIME as an external protocol, but then adds a bunch of junk characters following the TTIME command and you cannot get an estimate using this method. Sept 1, 1991 Page 7 TTIME Version 2.0 User Documentation GENERAL SUGGESTION #4 - Most terminal packages will allow you to press a key combination that allows you to enter a command to run from the DOS command line. You can press this key combination, then enter the TTIME command (and the file name or file size if you like) and it will run. Telix supports this option with the Alt-V key combination (press and hold the Alt key, then press the V key, then let both keys go. The bottom line will change to: DOS Command C> and you can then type in the TTIME command). GENERAL SUGGESTION #5 - If all else fails, most terminal packages will support a 'Shell to DOS', 'DOS Shell' or 'Command Prompt' option where the terminal stops temporarily, loads the DOS program and lets you type in a command just like normal. When you are done, you must type the word EXIT <enter> to return to your terminal software. Among the terminal packages that do suppport this are ProComm and ProComm Plus (Alt-F4), Crosstalk-XVI, Mirror and Mirror II (press Esc, then when the Command? prompt appears on the bottom of the screen type ru <enter> , and Telix (Alt-J). Among the software packages that TTIME just won't work with are: CompuServe's Professional Connection and Information Manager programs, older versions of Smartcom that came with many Hayes modems. You may find other software packages that it won't work with. If so, please try checking with me first, I may (by then) have a solution for you! Regarding WINDOWS: You CAN get TTIME to run under Windows 2.x or 3.x by setting up a TTIME.PIF file that specifies that it must run under a full-screen window and needs 256 K of memory to run. For some obstinate reason, TTIME won't operate in a window but must have the full DOS screen to work. I'm working on this one and hope to have a more Windows-compliant version soon. Sept 1, 1991 Page 8 TTIME Version 2.0 User Documentation CHAPTER THREE: Customizing TTIME One thing that we haven't mentioned yet is the display at the bottom of the TTIME display (below the ZMODEM/CIS B+ line) where it reports 'Estimated Cost'. This is a new feature added in Version 2.0 - the ability of TTIME to estimate the cost to send or receive a file! The program, as delivered, estimates the cost for a file transfer from CompuServe and assumes that you're making a local call (no toll or long distance charges) and that you're dialing a CompuServe Gateway number (not Tymnet or Telenet). You can, however, use the program TT20CUST.EXE to create a 'customized' copy of TTIME that will more accurately reflect your actual costs for transfering files. In fact, you could easily create several 'customized' versions, one for each pay-per-hour or long distance BBS you call, and get really accurate estimates for all the calls you make! Let's figure out how to customize TTIME so it supports the following: You call the BIG-PC BBS which charges $5.00 per hour for 1200 or 2400 bps access and $9.50 per hour for 9600 bps access. It's a long distance call for you, and Bell tells you that the approximate cost for a call from your home to the BIG-PC BBS is about 25 cents per minute. First, you need to calculate the 'per-minute' cost for these calls. At 1200 and 2400 bps, the cost is $5.00 per hour which translates to about 8.3 cents per minute ($5.00 per hour divided by 60 minutes). Add to that 8.3 cents the 25 cents per minute for the phone call and you get 33.3 cents per minute. At 9600 bps, the cost is $9.50 per hour which translates to about 15.8 cents per minute ($9.50 per hour divided by 60 minutes). Add to that 15.8 cents the 25 cents per minute for the phone call and you get 39.8 cents per minute. TT20CUST needs to have the figures given to it in the format: a.bbb where the cost is dollars (a), followed by a decimal point (.), then by cents and tenths of a cent (bbb). In our example, there are no dollars per minute, so that'd be a zero (0), followed by a decimal point and the approximate cost we figured. So, for 1200 and 2400 bps access, you'd use the figure: 0.333 and for 9600 bps access, the figure: 0.398 Sept 1, 1991 Page 9 TTIME Version 2.0 User Documentation since TTIME's estimates are 'rounded off' to the nearest tenth of a cent. You'd write these numbers down as you'll need them in a minute. I next recommend copying the TTIME20.BIN and TT20CUST.EXE files onto a blank, formatted floppy diskette. I recommend that you do this for several reasons: 1) If (heaven forbid) something goes wrong in the customizing process, all you've lost is a floppy disk that you can re- format; 2) This avoids the inevitable 'OOPS! I accidentally destroyed my ONLY copy of the unmodified TTIME.EXE program!' error that'll send you screaming back to me for another copy; 3) You should NEVER perform a patching or customizing job on the disk you bought, nor on your hard drive, JUST IN CASE! If you fail to heed my warning, probably nothing bad will happen. But, I want to warn you ahead of time that if it does, you can't blame me because I told you so! After you've done this, you start the customizing program by making the disk that TTIME20.BIN and TT20CUST.EXE are on the 'current drive' then the command TT20CUST. Assuming you've heeded my warning and copied the files onto your A: floppy drive, you'd type the following: A: <enter> TT20CUST <enter> First, the customizing program will make sure that there isn't a copy of TTIME.EXE already on your disk. If it finds one, it'll beep and warn you that it's about to destroy that copy. IF THIS HAPPENS, MAKE DOUBLE, DOUBLE SURE that this ISN'T your ONLY COPY before you press the 'Y' key to continue and destroy it! If you press ANY OTHER KEY EXCEPT THE 'Y' KEY, the customize program will stop dead in its tracks and you can then rename or move the current copy of TTIME.EXE so it'll be safe. Next, the customizing program will check to be sure you have the proper copy of TTIME20.BIN to customize. If you DON'T, it'll beep at you, warn you that your copy of TTIME20.BIN is not correct and abort the customizing process. This is for your own safety, since this error will only happen if someone has modified the TTIME20.BIN program without my permission or if you're trying to use the customize program on the wrong version of TTIME. If all else has been OK to this point, you'll be asked to enter the new cost amounts for 1200/2400 bps and 9600 bps estimates. This is where those two numbers you wrote down (0.333 for 1200/2400 bps and 0.398 for 9600 bps) will be used. Be sure that you enter them in the proper order. Sept 1, 1991 Page 10 TTIME Version 2.0 User Documentation Finally, after checking the numbers you've entered (to be sure that they match the necessary format exactly), and confirming that you've entered the proper amounts (it'll ask if it can proceed; if you press 'Y' it will customize the program, any other key will let you re-enter the amounts again), you wind up with a customized copy of TTIME.EXE that reflects what it costs YOU to transfer files to and from the BIG-PC BBS, including long distance charges! You could now rename this copy of TTIME.EXE to something else (like maybe TTBIG.EXE) and use it to estimate your costs in calling the BIG-PC BBS. Please note that if you customize a copy of TTIME, you should NOT give copies of it to anyone else. Distributing modified copies of TTIME violates my copyright, and is likely to make me very unhappy when I find out about it! Sept 1, 1991 Page 11 TTIME Version 2.0 User Documentation CHAPTER FOUR: Registration and Customer Support A lot of the information in this section is duplicated in the REGISTER.DOC file, but I want to lightly touch on why you must register your copy of TTIME if you want to continue to use it. TTIME is not free software. TTIME is a Shareware product (please read the SHR-WARE.DOC file for more details) and you are required to pay a registration fee of $10 if you find that you're still using TTIME after a reasonable evaluation period (say, 30 days). Why should you pay? Well: 1) Payment is required by law if you are going to keep using it. 2) I've put many hundreds of hours into developing, testing and improving the TTIME package from its humble beginnings to the product you see now. Payment for my labor is only fair. 3) A software package purchased in a store requires that you make payment up front, BEFORE you even know that the soft- ware will work the way you want it. With Shareware, you get a good trial at home first, before paying for the soft- ware. 4) Shareware depends on your honesty. If no one registers a shareware program, then the author will likely discontinue improving and supporting that program. It's up to you and your registrations to keep TTIME (and other shareware pro- grams) healthy and growing. Registered Users, in exchange for their $10 registration fee, will recieve: 1) My most heartfelt gratitude, and the undying appreciation of my wife (who's put up with me in front of the keyboard as late as 4:30am working on this release!) 2) The latest version of TTIME, with your registration number permanently emblazoned on it (so all who see it may envy you) 3) FREE UPDATES! All Registered Users will receive the next major release and/or bug fix version free of charge. This means, if I release a new version followed by a bug fix version (or vice versa), you'll receive two free update disks at no additional charge! Sept 1, 1991 Page 12 TTIME Version 2.0 User Documentation 4) FREE COMPUSERVE TIME! By special arrangement with Compu- Serve, ASP authors are allowed to offer to registered users an offer for a FREE CompuServe IntroPak, with your very own CompuServe ID number, password, and $15 in FREE CONNECT TIME that you can use to explore the CompuServe network (or, for that matter, to visit the ASP Forum for help, hints, support and other great ASP member product information). Furthermore, Registered Users can obtain preferential support of TTIME through several sources: - on CompuServe, by addressing CompuServe Mail to me at my User ID (76670,110) - By U.S. Mail, at the address shown on the registration form - Finally, I hope sometime in the autumn of 1991 to have the RGH Software Support BBS running. Registered Users will get the number when it's available For Disk Vendors, User Groups, SIGs, Software Libraries and BBSs that also wish to support the Shareware concept (and TTIME), there is a program called the 'Software Update Program' where for a payment of $10 you'll be entitled to FREE updates of all Shareware programs offered by RGH Software. ASP Associate Members in good standing (Vendor and BBS) need not pay this $10 fee - you'll automatically be entered in the Software Update Program. For non-ASP members, I cannot guarantee that you'll receive any updates or future releases. In my last disk mailing, fewer than 10% of all the vendors, BBS's and libraries I mailed disks to even bothered to send a letter or postcard back acknowledging that they got the diskette in the first place! With the cost of mailings increasing about every year or so, I find that I can no longer afford to send disks to people who don't show any interest in my products.

REVISION HISTORY: Version 1.0 - Original release in early 1990. Supported the XMODEM and YMODEM file transfer protocols, 1200/2400/9600 bps operation. Version 1.1 - Released in March 1990, added support for the ZMODEM and CompuServe B+ file transfer protocols. Version 1.2 - Died in beta testing. Never actually released to the general public. Version 1.3 - Released in late 1990. Since many users were complaining that TTIME routinely underestimated transfer times, I made it assume that file transfers would be less efficient. Version 1.3a - Also released in late 1990, this is a bug fix that repairs a rounding error reported by user Rip Strautman. Version 2.0 - Released September, 1991; the version you now have in front of you. Sept 1, 1991 Page 14
