.SH DESCRIPTION
.fi
Umodem uses the Christensen protocol to transfer files to
and from CP/M systems.

Umodem -- Implements the "CP/M User's Group XMODEM" protocol, the
TERM II File Transfer Protocol (FTP) Number 1, and the TERM II
File Transfer Protocol Number 4 for packetized file
up/downloading.

There is currently no batch transfer capability.  The program
writes logging data to a file in the user's home directory
called umodem.log.

The program will do a protocol file transfer with error checking
to or from a CP/M system running Ward Christensen's program MODEM
or one of its derivatives (MODEM7 or APMOD777 etc.) or any
program that uses the same protocols (e.g. ZPRO, TERM II).  Note that
executable and squeezed files must use the -sb or -rb options.

Umodem supports an interactive mode in which the user may perform
a number of Umodem-oriented functions without leaving Umodem.  These
functions (and their commands) are:
