Jim - 
If you use kermit to do the download, you can set the transfer 
mode to text instead of binary, and it fixes line endings on 
the fly.  If you have access to a copy of PC-NFS, it includes
the programs DOS2UNIX and UNIX2DOS that will do the conversion 
for you.

The following programs are filters that will work on a Unix system.
Feel free to hack them up.  

-----------------------------------------------------------
/**
 **  MJH 11/16/87
 **
 **  Read in an ASCII text file in Unix format,
 **  change all LF line endings to CR-LF
 **/

#include <stdio.h>

main()
{
int ch;

/* if ch is a LF, write out CR first */
while( (ch=getchar())!=EOF )
   {
   if(ch=='\n') putchar('\015');
   putchar(ch);
   }

exit(0);
}
-----------------------------------------------------
/**
 **  MJH 11/16/87
 **
 **  Read in an ASCII text file in MS-DOS format,
 **  change all CR-LF line endings to LF,
 **  and strip trailing control-Z
 **/

#include <stdio.h>

main()
{
int ch, lastch;

/* initialize lastch */
if( (lastch=getchar())==EOF ) exit(0);

/* if lastch isn't CR in a CR-LF pair, write it out & get next one */
/* note that this will write out CRs, if they're not succeeded by LFs */
while( (ch=getchar())!=EOF )
   {
   if(lastch!='\015' || ch!='\n')
      putchar(lastch);
   lastch = ch;
   }

/* flush lastch, unless it's DOS EOF (control-Z) */
if(lastch!='\032')
   putchar(lastch);

exit(0);
}
