involving the Telnet client. Third, reception of characters entered during output operations is delayed until after the
first ENQ/ACK handshake at the end of the line; this significantly improves break-mode response under RTE.
Unit options that may be specified are:
Option
Action
CAPSLOCK
Upshift lowercase input characters to uppercase
NOCAPSLOCK
Input characters are unchanged; default
LOG=<filename>
Enable I/O logging
NOLOG
Disable I/O logging; default
DISCONNECT
Disconnect the connection
Many HP operating systems require command input in upper case, although mixed-case output is supported. As
an aid to avoid toggling the host keyboard in and out of CAPS LOCK mode, the BACI provides this function locally.
The default mode is
NOCAPSLOCK
.
The BACI supports I/O logging to a file. Disabling logging also closes the log file.
The BACI may be manually disconnected from its associated Telnet session with the
SET BACI DISCONNECT
command. Otherwise, the connection will remain open until disconnected either by the Telnet client or a
DETACH
BACI
command.
Device configuration may be displayed with the following commands:
Command
Action
SHOW BACI
Display the device and unit configuration
SHOW BACI CONNECTION
Display the active connection status
SHOW BACI STATISTICS
Display the I/O statistics for the active connection
When a debug log has been established, tracing may be configured by specifying one or more of the reporting level
options:
Option
Reporting Level
CMDS
Command initiations and completions
CPU
Words received from and sent to the CPU
BUF
Data read from and written to the FIFO
XFER
Data receptions and transmissions
IOBUS
I/O bus signals and data words received and returned
The
CMDS
option traces the commands executed by the interface. The
CPU
option traces words received from
(control and write data) and sent to (status and read data) the CPU. The
BUF
option traces gets from and puts to
the internal FIFO buffers. The
XFER
option traces the words received and transmitted via the Telnet or serial
connection. The
IOBUS
option traces the I/O backplane signals and data received and returned via the interface.
Examples of the trace formats follow:
>>BACI cmds: [STF] Flag, SRQ, and lockout set
>>BACI cpu: [Lix,C] Received data = 102042
>>BACI buf: Character LF put to FIFO [29], character counter = 53
>>BACI xfer: Character 'R' transmitted from the UART
>>BACI iobus: Received data 000000 with signals STF
