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 (see page 21). 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

¾Connect 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]

¾Accessible 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)

¾Port 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,);

-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]
