SCS PTC-IIex, Manual

9 Packet-Radio
9.6.10 CText
Default setting: >>> Welcome...
Parameter: String of 249 characters, maximum.
The Connect text is transmitted when
CMsg
=1 and the PTC receives a connect.
As the
CText
input uses the command interpreter, a special convention for the <CR>-
character must be used. A <CR> is represented in the CTEXT string by a '#'.
>>> Welcome to %'s PTC-IIex DSP/QUICC System <<<
To leave a MSG, please connect %-8 (PTC-Mailbox)!
The string above would be given as:
pac:
CT
>>> Welcome to % 's PTC-IIex DSP/QUICC System <<<## To
leave a MSG, please connect %-8 (PTC-Mailbox)! < Return >
The % character serves here as a dummy for the appropriate MYCALL of the connected
channel. The SSID of the MYCALL is ignored. For example if DL1ZAM is the
MYCALL, then the PTC-IIex will give the following message to the connected PR
station:
>>> Welcome to DL1ZAM's PTC-IIex DSP/QUICC System <<<
To leave a MSG, please connect DL1ZAM-8 (PTC-Mailbox)!
The Command interpreter buffer is 256 characters long. Commands plus CTEXT
argument should not contain more characters, otherwise the CTEXT will be truncated.
9.6.11 DIGIpeat
Default setting: OFF
Parameter: OFF Digipeating disabled.
ON Digipeating enabled.
Enable or disable digipeating using the own station.
9.6.12 Disconnect
Ends an AX.25 link. If there is still data to be sent to the partner station, it is transmitted,
before the disconnect is carried out. If the
Disconnect
command is given twice, one
after the other, then the link is broken immediately (corresponding to
DD
in PACTOR).
9.6.13 FRack
Default setting: 5000
Parameter: X 1... 15,000, time in milliseconds.
FRack
sets the time in which a packet must be acknowledged. If the PTC-IIex sends a
packet and no acknowledgment is received within the Frack time, then the PTC-IIex
queries if the information has arrived.
The here given value of
FRack
is just the start value. The used value is dynamicly
recalculated during a connection using the formula: Frack = 2*SRTT*X. Hereby X =
