NTI RACK MOUNT CONSOLE TERMINAL WITH CONSOLE SWITCH

3.2.4 User Terse mode
This mode is especially useful when the SERIMUX is directly controlled by external software from a serial console (as a user
without administrative privileges), rather than being controlled by a user from a keyboard interface.
Entering short command strings performs functions similar to the user main menu commands. A [CR] – [LF] sequence ends every
string. The commands are not echoed; the SERIMUX returns to the serial console a specific answer if the command is
successfully accomplished or an error message otherwise.
Terse mode can be used only if the administrator configures a user port to enter into Terse mode at login. If a keyboard-based
user logs into a port intended for Terse mode operation, the following image will appear:

From Terse mode, a limited number of functions are possible;
3.2.4.1 Terse mode commands
¾ Connect to port
Send or type in:
[C] xx [Enter]
where xx is the port index number. The answer will be:
OK [CR][LF][LF][FF]
If an error occurs (i.e. the port is not accessible), the answer will be:
Err [CR][LF]
¾ Accessible host list
Send or type in:
[H] [Enter]
The answer may be, for example:
02,03,04,05,06,07,08,09,10,11,12,13,14,15,16 [CR][LF]
(the accessible hosts, separated by commas)
¾ Port info
Send or type in:
[P] xx [Enter]
where xx is the accessible port index number. The answer may be, for example:
04,H, 9600,8N1 ,N,QS,1X [CR][LF]
where the comma separated fields stand for:
- port index number;
- port type: U or H for User or Host;
- port baud rate;
- data bits (5..7), parity (N, E, O for None, Even, Odd), stop bits (1, 1.5, 2, 2.5);
- flow control (N, H, S, B for None, Hard, Soft, Both respectively);
- in-band (soft) flow control Xon and Xoff characters (in this example Xon = [Ctrl+Q] and Xoff = [Ctrl+S]);
- disconnect sequence length and sequence (i.e. “0 ” for none, “1X ” for 1-char [Ctrl+X] sequence, “3```” for 3-char ```
sequence);
If the port is not accessible to the user, the answer will be:
Err [CR][LF]
