Greetings from the REALM.... Over the past couple of nights I've spent a couple bill-zillion hours trying to figure out how to hook my ST to my Portfolio. It seemed easy enough at first until I realized there is no way to send a file to the Portfolio without doing some strange things. I didn't want all my downloading time and problem solving to be wasted on just one portfolio so here's what I learned. The arc file contains the programs neccessary to download your first xmodem program, after that your home free. Your Arc should have contained the following: READTHIS.TXT (if your not reading this...Hmm! never mind) CHKSUM.COM (provides the checksum of bytes in a PF program.) HEXBIN.COM (switchs a Hexadecimal code into Binary code) TMXM2.HEX (a shareware terminal program for Xmodem and Text transfers) You need to provide the following items: Null Modem Cable (I think you can get a regular DB9 to DB25 Null Modem cable both ends female. If not buy a joystick extension cable at Radio Shack and hack off the Male end. Buy a DB25 Female end and a cover. Use a continuity tester to help connect the pins. There is a cable file in this library.) The Control Panel (the one that should have come with the computer, should be labeled CONTROL.ACC and contain both the PRINTER and RS232 Configure buttons. Set the RS232 to 1200 Baud, None, Full, On, Off, Off. Now set the Printer to Modem and that should be it for the control panel. A Control+Z txt file (You need to make a text file with the code for Control+Z or the code that lets the Portfolio know your finished. I went to the buffer in Flash, pushed Control Z, it made a weird small e and I saved it as Z.TXT) Hang in there, it took me forever to figure this out. I tried about ten different Terminal programs, read a couple gillion files and realized no one really knows how to do it. The bulk of the Idea come from a text file by ABGRAF (Thanks!) but I couldn't find a modem program that wouldn't mess up the files in transmission. Here is the idea at last. You will double click on the file you want to transfer (after installing and setting the control panel), then click "print" (it will be sent to the Serial Port) which in turn will be received by the Portfolio. Acting with cat like reflexes you then have to print the Control Z file to end the transmission. The Step by Step Part.......... A. First make sure that both Serial Ports are set the same. Set your control panel as stated above. Set the Portfolio's Serial Port buy entering the Setup Mode and setting the RS232 port to match the Control Panel. B. On the PF, type: COPY AUX CHKSUM.COM [DO NOT PUSH ENTER] On the ST, Double Click on the CHKSUM.COM file [DO NOT PRINT YET] Push ENTER on the PF then pick PRINT on the ST. (It's quick!) When the ST is Done IMMEDIATELY! Double Click on the Z.TXT file and PRINT it. If you had all the connections correct the PF should say "1 file copied" if it says "error" you didn't get the Z.TXT file fast enough or the connections are wrong. Try a couple times and if it still doesn't work double check the cable and the terminal settings. If your PF is frozen push the REBOOT on the bottom. C. If it seems to have worked (check the file size) you can type on the PF: CHKSUM CHKSUM.COM the response should be 309A. If you don't get this try again. Repeat the above procedures for both remaining files HEXBIN.COM and TMXM2.HEX. There respective CHKSUM values are 4080 (HEXBIN.COM) and 0F7D (TXMM2.HEX). D. Glad you could make it! If you managed to get those three files to the portfolio you are in good shape the rest is easy. On the PF Type: HEXBIN TMXM2.COM almost a minute later the C> should return. When the C> returns type: REN RESULT.OUT TMXM2.COM (it's CHKSUM should be FC6D). To run the program just type TMXM2 and the results should allow you to use normal XMODEM transfer from this point on. Gosh! It seems pretty easy now that I look back. Hopefully you where able to get your PF up and runnen, if not you can contact me directly via GEnie Mail Address: REALM. Good Luck! Until later...
