6.5.7 Lock Messages
When information is transmitted to the host computer, the keyboard locks to
prevent further data entry until the 7535 receives a reply. A locked state is
indicated by either “LOCK-B” (base) or “LOCK-H” (host) in the lower left
corner of the display.
When the reply is received by the 7535, the lock message disappears and the
keyboard can be used again.
6.5.8 Control Commands
A group of <CTRL> key commands can be used within TESS to dictate how the
7535 will operate under a variety of conditions.
• <CTRL> <P> – Reprints the last print page sent from the host. This key
combination will not print anything if a print page from the host was not
previously received at the 7535 hand-held.
• <CTRL> <S> – Displays the 7535 status continuously. Below is a sample
status line as it might appear at the bottom of your screen:
Lock-B/Lock-H fld enh “
application name ”
• <CTRL> <W> – Displays the 7535 status when the unit is in “Lock B” or
“Lock H” mode. The status line would be similar to the sample above.
• <CTRL><T> – Displays the 7535 status with the terminal number instead
of the name.
Lock-B/Lock-H rep “
terminal nn ”
• <CTRL> <H> – Displays a menu of available hosts.
6.5.9 Resetting A TESS Session
Resetting a TESS session requires that <CTRL> C be pressed three times within a
two second period to generate the “RESET – User request” message.
• Press and hold down the <CTRL> key, and press the <C> key three times
within a two second period.
• Press <ENTER>.
This procedure restarts the TESS session without affecting the rest of the 7535.
