ham/7plus 225nb3 NetBSD

7plus is an uuencoder-like file coder for use in Amateur Packet Radio BBS S&F of binary data files. The Packet Radio protocol (AX.25) utilizes 8 bits for data transfer whereas most standard terminal programs only use a 7 bits alogarithm. The result is that only 87.5% of the available bandwidth is utilized.

7plus fully exploits the capacity of the network by using all 8 bits and hence increasing data throughput. Furthermore, it uses alogarithms which checks for data integrity, detecting, reporting and, whenever possible, correcting data transmission errors that may have occurred due to noise or loss of signal with minimal overheads.
