This BBS program is written mostly in BASIC with just enough machine code to allow a 300/1200/2400 baud modem to transmit and receive at full speed. The main purpose for writing a BBS in BASIC is for ease of modification by the you the SYSOP. If you can do a little BASIC programming, then you should be able to make almost any changes to the BBS you may want. But if you ever do need or want any help in a making a modification, feel free to ask me about it.
