The Emulator. in addition to receiving the selection codes, transmits them. The selection code is
automatically transmitted in the appropriate manner when the Send with Device Selection (SS)
command is used. The card punch or printer is selected through the operator's response to the
DEVICE: prompt. When transmitting to an IBM host, SS should not be used since the selection
code is not understood.

The output device selected must be ready. If it is not, an EOT character is transmitted as a response
,. to the block of data.
2.2.15 AUDIBLE ALARM. The audible alarm feature on the IBM 3780 and 2780 alens the
operator, with an audible alarm, that the terminal requires attention. Indicator lights on the terminal
indicate the reason for the alarm. When the Emulator requires attention, messages that correspond
to the meaning of the IBM 3780 and 2780 indicator lights are logged on the operator console or in a
log file. Situations that prompt these messages are indicated in table 2-3.
