You can now switch between sessions using Alt-N. Also note that the status line at the bottom indicates which session is active.
Note taht if you want to log out, and then log in again to another machine, it is faster (on some PCs a lot faster) to first open a new session, then switch back to the original session and log out. After all, in this case there is no need to re-read the executable and configuration files from disk, and PC disks aren't the fastest things in the galaxy.
Press Alt-F to start a FTP session, now use
cd to change to the desired directory on the PC (also,
cd a: will take you to your floppy disk drive).
You will probably want to transfer all files in binary mode, so type
bin.
Note that all transfers are treated as viewed by the workstation, so get reads from the PC, and put writes to it.
set printer=hp5 to select the printer, although a useful
default is set in autoexec.bat.
There is also a lpq utility to view the printer queue, and lprm to remove jobs from the queue (any job send by the same PC can be cancelled; DOS doesn't know about user authorization).
