The attached programs are totally free shareware. I currently use them while transmitting/receiving data between DOS, UNIX/XENIX, and MAINFRAME storage areas. These are great to use with Kermit. Below is a brief description of each program. Note that I have com- piled and tested each one in the following areas: UNIX/XENIX operating system, System 5, release 3; DOS, Microsoft Version 5.1. filecmpr.c : beats any file compressor I have seen in Unix. Compressing is a little slow but decompression is quite fast. I wish someone out there had the time to expand this into an arc/zip kind of utility so we could send archive files between DOS and UNIX. chgxmitf.c : creates/uncreates a printable ASCII file from any kind of input file. Use this to create good transmittable files that Kermit and other utilities will not corrupt. split_f.c : breaks up/puts back together large files for transmission. Great if you are transmitting over a noisy line and have a big file to transmit. See attached split_f.doc. I have not given any usage info here since you can get that by typing the executable name by itself. To compile in Unix: just do a 'cc'. In DOS, set up environment flag DOS; example cl -DDOS filecmpr.c with Microsoft; other compilers should have no problems with these. I created chgxmitf.c from scratch, the others were originally secured from DOS BBS's and modified to work in UNIX/XENIX. Have fun with these. Martin Katz 1600 N.
