lrzsz

Receive/Send files via X/Y/ZMODEM protocol (unrestrictive)

This program uses error correcting protocols to send/receive files over a dial-in serial port from a variety of programs running under PC-DOS, CP/M, Unix, and other operating systems. lrzsz is derived from the last unrestricted version of Chuck Forsberg's rzsz package. lrzsz is covered under the GNU copyleft.
