1.5.7 Protocols
TCP/IP for VXI-11, HTTP and RPC communication
UPD and TCP/IP for RPC Port Mapper commands
Modbus TCP/IP for Modbus RTU conversion
Raw Socket for telnet compatible IP packet communication
1.5.8 Raw Socket
The 90x9's Raw Socket configuration is set to the following values:
Port 23
Sockets 4
Echo Off
Prompt None
Timeout 120 seconds fixed
Logon message Message equal to *IDN? response.
Terminator Linefeed character
Carriage Returns Client generated carriage returns are ignored.
Backspace Prior character deleted up to the start of the buffer.
Echo On command Cntl-E
Echo off command Cntl-F
The Raw Socket connection will be closed if there is no communication for 120
seconds. To prevent the Raw Socket from timing out and disconnecting, the
client can issue a no change message like space-backspace or a Cntl-E-Cntl-F
sequence, on an occasional basis, to restart the timeout counter.
If Echo was enabled, all client character will be echoed back to the client. The
echo sequence for a backspace is a BS-space-BS to visually wipe the deleted
character off of the telnet client screen.
