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 TNC at 300 baud on the serial port with these computers.
NOTE:
When using the above program, 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.
When making the connecting cable from TTL port of the MFJ TNC to the I/O
port of the Commodore computer you may use the wiring information given on
page 2-3 in this chapter. 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 TNC serial port faster
than 1200 baud.

for packet radio and packet bulletin board service can also be used with the MFJ
TNC . Note that these type of programs will not support printing of graphics to
