Display parameter values

Syntax: P <CR>

The PARAMETERS command puts out a list of the current parameters and some channel statistics. Additionally, the links as shown with the <L> command are displayed.

Example:

=> P <CR>

po id td qso usr tifr rifr tkby rkby qty mode       links  ssids  time

8  7  40   8  8  184   36   34    1   92 1200*+

The single columns mean:

po: Port number

id: Port SSID, on interlink-only ports "—"

td: TxDelay in 10 ms units

qso: number of QSOs on this port, internode QSOs are also counted

usr: number of stations heard on this port (since 3 mins)

tifr: transmitted I-frames within the last 10 mins

rifr: received I-frames within the last 10 mins

tkby: transmitted kilobytes within the last 10 mins

rkby: received kilobytes within the last 10 mins

qty: quality of the channel; this is updated every 10 mins, but not if there was nothing to send.

mode: Baudrate on this port, additionally:

	"c" KISS: CRC-Mode, HDLC: Software-DCD (depends on hardware)
	"d" fullduplex
	"t" xternal TX-Clock
	"r" external RX-Clock
	"z" NRZ mode
	"m" DAMA master
	"s" port is synchronized
	"u" port is user port
	"y" autosysop
	"+" 8 Mhz CPU-Clock (RMNC)
	"!" 12 Mhz CPU-Clock (RMNC)
	"#" 16 Mhz CPU-Clock (RMNC)

links: see <L>-Command

When counting the I-frames, re-iterated frames and frames which got lost due to DISC are not counted. The kilobyte statements are only the contents of the acknowledged I-frames, re-iterations are not counted, too. Thus, this is the genuine net data rate.

Set Parameter values

Syntax: P I <value> or P S <value> <port> or P T <value> <port>

The PARAMETER command is used to set up the TxDelay, SSID and the node timeout of a specified port.

"P I <n>" sets the node timeout to <n> minutes where a range from 60 to 255 is valid. n=0 (recommended) disables the timeout.

"P T <n> <port>" sets the TxDelay of port <port> to <n> in 10ms units.

"P S <n> <port>" sets the SSID of port <port> to <n>. When an already-set SSID has to be deleted, <port> has to be 16.

Why do we need SSID’s ? They do two jobs: Only on ports which do have a SSID, everyone is allowed to connect. Exclusive interlink ports therefore should not have SSID’s (exception: links to NET/ROM partners, see appendix). The SSID is also needed for routing purposes, if a user who is not in the MHeard-list shall be connected on a specified port. The connect then needs to go via the according SSID, i.e. via <nodecall>-<port-SSID>.
