Hi,
Actually, when i need to copy a file from my SCO 5.0.4 box, i use the ftp command, like the following:
While on my PC, i open dos command(known as MS-DOS prompt) window, and i run ftp with the ip address of my SCO box, then login and go to the needed directory where i type: get filename. You can use the help command inside ftp to have a list of commands you can use.
Or, as i checked the man doscp, you can try to copy the file on a disk using doscp command like the following 2 examples:
example1: doscp /tmp/myfile.txt /dev/fd0:/docs/memo.txt
example2: doscp /tmp/f1 /tmp/f2 /dev/fd0:/mydir
Where fd0 is most probably the name of the diskette
N.B.: check the man doscp
Regards,
Christian
