MFJ-1278B MULTI-MODE COMPUTER INTERFACING

Commodore C64, C128 and VIC-20

The optional Starter Pack for the C-64, C-128 and VIC-20 is available from MFJ Enterprises, Inc. or from any dealer of MFJ products. Included in the Starter Pack is a cable to connect the MFJ-1278B TTL port to the user I/O port on the Commodore computer. Also included with the Starter Pack is a terminal program. The terminal program allows compatibility between the MFJ-1278B and the Commodore computer. To order, specify MFJ-1282B for software on disk or MFJ-1283 for software on tape.

If you do not have the MFJ Starter Pack, then you may use the BASIC communications program given in the Programmer's Reference Guide published by Commodore. Use the program listing for "true ASCII," as these computers use a modified ASCII format internally. You will probably want to run your MFJ-1278B at 300 baud on the serial port with these computers.

NOTE: When using the BASIC communications program above, you must first use the "COMMODORE" key to shift to lower case before using this program. Also line 200 should read For J=0 to 64:T%(J)=J:NEXT.

The information given on page 5 of this chapter is used to make a cable for use with the BASIC communications program mentioned above. However, do not use pin E connection for this program.

IBM PCjr

The IBM PCjr has a built-in terminal program in the BASIC cartridge. Start this program by typing TERM. Refer to your PCjr BASIC manual for details on this program. For best results with PCjr, do not run the MFJ-1278B serial port faster than 1200 baud.

IBM and Compatible Computers

The optional Starter Pack, (MFJ-1289) for the IBM PC and compatible computers is available from MFJ Enterprises, Inc. or from any dealer of MFJ products. Included in this Starter Pack is a graphics terminal program. This program allows compatibility between the MFJ-1278B and the computer. Also included is a cable used to connect the MFJ-1278B to your computer. The MFJ-1289 program allows you to transmit and receive 16 gray level FAX as well as color SSTV pictures. The MFJ-1289 also allows for display of these signals on the computer screen. It will also store the pictures on disk for later viewing or transmitting. This software also sets up compatibility between the MFJ-1278B and the computer when operating the other mode, that the MFJ-1278B has to offer.

You may also use many commercial, "shareware" and public- domain terminal programs for the IBM PC and compatible computers. Special programs written for packet radio and packet bulletin board services can be used with the MFJ-1278B. Note that these types of
