Subject: Basic "MBOOT" program

Andrew: I think that this program will do what you are looking for.
       Let me know how it truns out...

80 REM It will work with the Xerox as well as the Kaypro
 90 REM FOR THE KAYPRO

     BMODEM.DOC
THIS IS A VERY BASIC MODEM PROGRAM FOR THOSE WHO DON'T HAVE
THE PATIENCE FOR DEALING WITH MBOOT3.
THE ONLY LINE THAT NEEDS ALTERING IS 280 IN WHICH YOU PUT
MODEM PORTS IN (HEX OR DEC) AND THE RECIEVE & SEND BIT MASKS.
When you run the program it will act like a very dumb terminal
Use it to log on and setup XMODEM to send you a 
better modem program or USQ.
CTRL E asks you for the filename to be received.
An ESC will transmit CTRL C to the remote machine.
A tilde will transmit a CTRL S.
To dial the Hayes modem enter ATDT <phone number>

Altered for the Xerox 820,820-II, and 16/8 on 12/07/84
