If DHS (direct handshake) is set on a given port, the port, when selected, will pass its

DSR signal directly back to port 0’s DTR signal, and port 0’s DSR signal will pass directly

to the DTR signal on the selected port. DHS cannot be set on port 0. This is useful for

dealing with modems.

** For parallel units only. These are the only parameters used by parallel units. Ignored if

set on a serial unit. These parameters cannot be set for port 0.

Copy from buffer command

The copy command is useful for sending multiple files of data while only storing one copy

of the data. The command requires an additional operand of the number of times to copy

the buffer. The format of this command is the prefix + the port number + a two digit

decimal number specifying the number of copies to be made. The zero buffer command

may be used to cancel a copy in progress. The maximum number of copies allowed is 14.

Entering the copy command with > 14 copies causes it to be ignored.

Example of the copy command

To use the copy command, first connect to the port you wish to send copies out of. Use

the Z (Zero Buffer) command to clear the buffer, and then send the first (original) copy.

Then issue the copy command to send the remaining copies. After sending the copy

command you may connect to other ports without disturbing the copying process.
