The version of the Public Domain Software, MODEM7 contained on this disk has been specifically modified for use on an NEC PC- 8801A Computer ONLY. In order to operate it, you must have NEC Version-Release B CP/M for the PC-8801A, because it utilizes a special INSTALL8 RS-232C Communications Port Driver, MODEM7B.DRV, which can only be installed on the latest Version-Release. If you do not know which version you have, boot your MASTER CP/M system disk and, at the A> prompt, type: VERSION8 If the response is: VERSION8? Then you do not have version B and you need to send in your master CP/M system disk with a MONEY ORDER or CASHIER'S CHECK for $15.00 for the CP/M Version-Release B update to: NEC CP/M Version-Release B Update 700 Nicholas Boulevard, Suite 10 Elk Grove Village, Illinois 60007 The small cost covers printing, duplicating and return shipping costs that we incure in performing the update. BE SURE TO PLACE YOUR MASTER CP/M DISK IN A COMPUTER DISK MAILING ENVELOPE THAT IS VERY RIGID. We cannot be responsible for the condition of your disk before arrival here. It is also suggested, though not manditory, that you send the disk with verification back to you of our receipt of the disk, ie. Certified Mail. Most importantly, keep a record of your serial number, in case Murphy's laws take effect before we receive your disk. If the response is: The currently booted CP/M has release 2.0 of the CBIOS. Then you are ready to begin using NECMDM7. How to use NECMDM7, the PC-8801A version if the Public Domain Modem7 program: You must use your NEC Version-Release B CP/M-MASTER disk to make a new blank disk into a formatted, bootable system disk that will become your NECMDM7-WORKING disk. Then use DISK8.COM to copy the files from the NECMDM7-MASTER disk onto your newly made NECMDM7-WORKING disk. You will also need to copy the programs INSTALL8.COM and SUBMIT.COM from off of the CP/M-MASTER onto it. To do so, first, consult your CP/M Manual for how to use the DISK8 program to Format (@ 256 bytes/sector) and how to Copy System Tracks from the CP/M-MASTER to the NECMDM7-WORKING disk. Second, be sure the DISK8 program is still running and you have the Main Menu displayed on the screen. Remove the CP/M- MASTER disk from disk drive A and place the NECMDM7-MASTER disk in disk drive A. Insure that disk drive B contains your NECMDM7- WORKING disk. At the Main Menu, enter the letter that corresponds to the TRANSFER FILES selection. A new menu will appear. At this menu choose the letter that corresponds to TRANSFER FILES. When the file transfer is complete the disk drives will silence. At this point, only remove the NECMDM7- MASTER disk from disk drive A and place the CP/M-MASTER disk in disk drive A. The program should still be at the FILE TRANSFER SUBMENU. The final steps are: 1) Choose the letter that corresponds to the FILE NAME selection, then enter INSTALL8.COM . 2) Now, choose the letter for TRANSFER FILES again. When that file transfer is done, simply repeat the last two steps to transfer SUBMIT.COM. That completes the creation of your NECMDM7-WORKING disk. Place it in disk drive A. To simplify installation of the MODEM7B Communication Port Driver, a SUBMIT file called STARTUP.SUB is present on this disk. Before running the program, though, be sure that the RS-232 jumper at the rear of the PC-8801A is set to jumper position 5. This will allow communications at 300 baud, and if your modem is capable, NECMDM7 can switch it upon your command to 1200 Baud. The NECMDM7 program can be operated by entering: SUBMIT STARTUP The main menu will display giving you all the options of it's mother program, MODEM727, as last updated by CP/M user Irv Hoff. Any time when the Command>> prompt is displayed you may type in M to view the menu again. Choose T,L, or E to enter Terminal, Terminal with Local Echo, or Terminal with Echo, modes to communicate. Depressing and holding CTRL and then E simultaneously will bring you back to the Command>> prompt. At the Command>> prompt you may type CPM to exit NECMDM7. Have fun communicating.
