1.5.5.1 Echos and Prompts
The 2363 returns a prompt when ready for the next command. If Echo is
enabled, the prompt character is lined along the left edge of the screen. The
CNTL-E and CNTL-F commands turn echo on and off and change the
prompt sequence and message terminators as follows:
Command Echo
CNTL-E
CNTL-F
The user should not attempt to send a new command until it has completed
the current command. Echo mode changes are immediate.
1.5.5.2 Service Request Message (SRM)
The 2363 emulates the IEEE-488.1 SRQ line by transmitting an asynchronous
Service Request Message (SRM) when it is not busy processing a message
and when an enabled Status Byte bit becomes set. The SRM format is:
SRM n <LF>
e.g. SRM 96
1024 bytes
Message
On Response
Off Response
where n is the decimal value of the Status
Byte Register
indicates bits 5 and 6 are on.
