number of rows. Then click the Insert Row# button to insert a

blank row. This row must be filled in with all data required.

Note that when adding or deleting rows of a Host Connection

Table, make sure to click the Insert Row# or Delete Row#

buttons within the brown section of the Terminal Client, not the

buttons at the very bottom of the main table.

In order to delete a row of the Host Connection Table, enter a

number in the box between 1 and the highest number of rows.

Then click the Delete Row# button to delete the row. Once a

row is deleted, it cannot be restored without inserting a row

and entering the data again.
