# This is a shell archive, meaning:
# 1. Remove everything above the #! /bin/sh line.
# 2. Save the resulting text in a file.
# 3. Execute the file with /bin/sh (not csh) to create the files:
#	README
#	xmodrec.1
#	xmodtran.1

#	add.c

To create the two xmodem programs, run:
	make all

To (compile and) install run:
	make install

There are two manual files: xmodtran.1 and xmodrec.1

The two compiled programs, xmodrec and xmodtran, will be moved to the
/usr/local directory.  If this is not where you want them, change the
Makefile $PATH variable to what you want for your system.

The programs are being used on a VAX 750 with BSD 4.2.  They are used
to transfer data between PCs and the VAX.

If you have any questions or comments, send UUCP mail to:

.TH XMODREC 1
.SH NAME
xmodrec \- receive file using XMODEM protocol
.SH SYNOPSIS
.B xmodrec
[
.B \-t
] filename
.SH DESCRIPTION
.I Xmodrec
is used to receive a file from another computer, ie, IBM PC or look-alike.
The computer from which the file is to be received must also have the
XMODEM protocol.
.PP
This version of XMODEM uses the checksum method of error detection.
.PP
Options:
.TP 6
.B  \-t
Remove the carriage returns from the incoming data.  Also removes the ^Z
end-of-file marker and any data after it.

.TH XMODTRAN 1
.SH NAME
xmodtran \- transmit a file using XMODEM protocol
.SH SYNOPSIS
.B xmodtran
[
.B \-t
] filename
.SH DESCRIPTION
.I Xmodtran
is used to transmit a file to another computer, ie, IBM PC or look-alike.
The computer to which the file is to be transmitted must also have the
XMODEM protocol.
.PP
This version of XMODEM uses the checksum method of error detection.
.PP
Options:
.TP 6
.B  \-t
Adds carriage returns to each line of data being transmitted.  Some computers
require that the text file have a CR/LF at the end of each line.
