- DESCRIPTION OF COMMANDS
- =======================
-
- CAUTION: Every software depends on a proper setting of all parameters.
- The value of many parameters can change according to the used digipeater
- and/or baudrate. Therefore please read and accept hints from your local
- digipeater sysop. Further information can be found in your local packet
- radio mailbox.
-
-
- ESC A [0|1] Automatic insertion of LINEFEED-character <LF> after
- CARRIAGE RETURN <CR> (1=Yes, 0=No).
- Default: 1
-
- ESC B [<n>] If during this time no poll from the DAMA-master is
- received, the DAMA-mode is switched off. B 0 disables
- DAMA generally, although not needed, because DAMA is
- detected automatically and if no DAMA-master is active,
- the DAMA-mode is off. The display is in the following
- format: "initial value (actual value)".
- Example: "120 (93)" Default: 120
-
- ESC C [Call] Starts a link setup (connect) on the current channel.
- If you specify a digipeater path no 'v' or 'via' is needed.
- While on channel 0 this command sets the destination of
- UI-frames.
-
- ESC D If a connection is active on the current channel, it
- will be disconneted. If there are any unacknowledged frames
- left, the disconnect is delayed until the last frame is
- acknowledged. A direct disconnect can be forced with a
- second 'D'-command.
- If the 'D'-command is entered during link setup or during
- disconnect, the TNC immediately returns to disconnected
- state and sends a DISC-frame to cancel transmissions of
- the remote station, if the TNC was not able to decode
- frames of the remote station.
- If the 'D'-command is entered in disconnect state, all
- parameters are initialized to the default values stored
- in channel 0.
-
- ESC E [0|1] This command controls the ECHO of characters typed.
- 1=Yes, 0=No.
- Default: 1
-
- ESC F [<n>] FRACK is the time between the transmission of an information
- packet and the acknowledgement of the remote station.
- Values >15 will be the initial round trip time (IRTT) and
- the unit is 10 milliseconds.
- For values <16 the unit is seconds and the value will be
- translated to the IRTT by multiplying it with 100 and dividing
- it through parameter A3.
- Default: 250
-
- ESC G [0|1] Not applicable in terminal mode, used for polling of
- data in hostmode.
-
- ESC H [<n>] Configuration of the heard list.
- Examples:
- H - display of heard list
- H 0 - disable update of heard list
- H 1 - enable update of heard list
- H 2 - erase heard list
- H n - Set maximum number of calls in heard list
- (n > 2)
-
- The last heard calls will be stored, old entries will
- be overwritten. The heard list is resident, it is not
- deleted by reset or switching off.
-
- CAUTION: If the heard list contains many entries, a restart
- may take some time because of internal buffer linking
- during startup.
- Default: 0
-
- ESC I [Call] Input of own callsign (MYCALL). The default value in the
- EPROM is all spaces. After disconnect the callsign of channel
- 0 is copied to the actual channel.
-
- CAUTION: Without a callsign the TNC will not transmit
- anything.
-
- ESC JHOST[0|1] This command switches between terminal- and hostmode.
- The hostmode is used by special programs.
-
- ESC K [<n>] This command controls the clock, calendar and the stamp-
- function.
- Examples:
-
- K - display stamp and date/time
- K 0 - disable stamp
- K 1 - enable stamp for status messages
- K 2 - enable stamp for status messages and
- for monitor frames.
- K 20.02.88 - set date, european format
- K 02/20/88 - set date, american format
- K 17:36:00 - set time
- Default: 0
-
- ESC L [0..10] This command shows the link state of one or of all (no
- parameter specified) channels. Following information will
- be displayed: connect-path (callsign and digipeater path),
- number of received frames, number of unsent frames, number
- of unacknowledged frames and the retry counter. The currently
- activated channel will be marked with a '+'.
-
- ESC M [IUSCN+-]This command controls the display of monitor frames. The
- parameters specifiy the type of frames which shall be
- displayed.
- Examples:
-
- N no frame display
- I information-frames
- U unproto frames
- S supervisory frames
- C display during active connection
- + <list of up to 8 calls>: only frames of these
- stations
- - <list of up to 8 calls>: no frames of these
- stations
-
- A combination of '+' and '-' is not possible. If specified
- '+' or '-' must be the last parameter before the callsign
- list. Without a callsign list, the current list is deleted.
- Default: UI
-
- ESC N [0..127] Maximum number of retries (0 means try forever). This value
- can be changed for each channel independently, but will be
- restored to the value of channel 0 after reset or disconnect.
- Default: 10
-
- ESC O [1..7] Maximum number of outstanding packets (MAXFRAME). This value
- can be changed for each channel independently, but will be
- restored to the value of channel 0 after reset or disconnect.
- Default: 2
-
- ESC P [0..255] Value for p-persistance algorithm. In DAMA-mode a value of
- 255 will be used.
- Default: 32
-
- ESC QRES Cold boot, uses default values stored in EPROM.
-
- ESC R [0|1] This command controls the digipeat function.
- 1=Yes, 0:No.
- Default: 1
-
- ESC S [0..10] Activation of a channel (0= unproto channel)
- Default: 0
-
- ESC T [0..127] Delay between start of transmission and start of data
- (TXDELAY). The unit is 10 ms. Please adjust to the lowest
- possible value.
- Default: 25
-
- ESC U [0|1|2] This command controls the connect text feature (CTEXT).
- This text is sent if a remote station connects.
- The text will remain stored even if the ctext mode is
- changed. If mode 2 is selected and the terminal mode is
- active, a packet received with '//Q' at the beginning will
- disconnect the remote station. In hostmode this function is
- disabled.
-
- Examples:
-
- U 1 Text enter CTEXT
- U 1 CTEXT will be sent
- U 2 (text) CTEXT and //Quit-function!
- U 0 disable CTEXT
- U display CTEXT
- Default: 0
-
- ESC V Displays the actual version of the software
-
- ESC W [0..127] Value of the slot time of the p-persitance algorithm. The
- unit is 10ms.
- Default: 10
-
- ESC X [0|1] This command allows to disable the transmitter.
- 0= disable, 1= enable.
- Default: 1
-
- ESC Y [0..10] Number of channel which will accept an incoming connect
- request. The display format is "max. channels (used
- channels)". Only works correct if the SSID are the same
- on every channel.
- Example: "4 (0)" Default: 4
-
- ESC Z [0..3] With this command flow control and XON/XOFF-protocol can
- be activated.
- If flow control is activated no charcater is sent to the
- terminal during data input.
- If it is disabled all received data is sent immediately.
- If XON/XOFF protocol is activated data output can be stopped
- using <CTL-S> and continued with <CTL-Q>.
- Examples:
-
- 0 flow off , Xon/off off
- 1 flow on , Xon/off off
- 2 flow off , Xon/off on
- 3 flow on , Xon/off on
- Default: 3
-
-
- Additional commands are available which starts with '@':
-
-
- ESC @A1 [<n>] SRTT calculation: change/display value for a1. Default: 7
-
- ESC @A2 [<n>] SRTT calculation: change/display value for a2. Default: 15
-
- ESC @A3 [<n>] SRTT calculation: change/display value for a3. Default: 3
-

- ESC @M [0|1] 7-bit oder 8-bit terminal mode.
- In 7-bit mode a control code conversion is active, too
- which will display control codes with a leading '^'.
- In 8-bit mode all control codes are sent without translation.
- CAUTION: disable XON/XOFF in your terminal-program, otherwise
- a XOFF will stop the data flow.
- Although 8-bit mode is the default mode the real advantage
- of TheFirmware is the *WA8DED HOSTMODE*. It is recommended
- to use it together with a special terminalprogram instead of
- using the terminal mode for binary transfers.
- 0=7-Bit; 1=8-Bit (only terminal-mode)
- Default: 1
-
- ESC @T2 [<n>] Time between the receiving of a packet and the transmission
- of the acknowledgement (timer T2).
- Default: 150
-
- ESC @T3 [<n>] Time after which the connection is tested, if no data
- transfer was done (still alive timer, timer T3).
- Default: 18000
-
- ESC @V [0|1] Test if entered callsign is a valid callsign
- (1=Yes, 0=No).
- Default: 0
