9 Packet-Radio
RETRY if RETRY is > 2, otherwise X = 1. SRTT is the “Smoothed Round Trip Time”. X
is generally 1 under link establishment condition.
9.6.14 Help
Lists all the Packet-Radio commands.
9.6.15 JHOST
Default setting: 0
Parameter: 0 Exits the hostmode.
1 Starts the hostmode.
4 Starts the CRC hostmode.
5 Starts the extended CRC hostmode.
Switching to the hostmode.
The command is used by the hostmode software to switch to the hostmode. During
normal operation within the terminal mode this command has no function. For more
information about the PTC-IIex hostmode refer to chapter 10 , page 131 .
It is strictly forbidden to enter the
JHOST
command in the initialization file of the
hostmode programs! Hostmode programs switch to the hostmode independently.
9.6.16 KISS
The KISS-Mode is activated with the commands
KISS
or alternatively
@K
out of the
normal command mode. This usually happens automatically by the KISS-PC-software or
a KISS capable controller (e. g. TNC3). The KISS-mode is terminated by a system reset
(power off/on cycle), but can also be terminated by software with sending the decimal
byte sequence 192, 255, 192. The termination by sending the byte sequence is usually
done automatically by the software as well, and may just once be configured correctly in
the setup of the program.
9.6.17 MAXframe
Multiport
Default setting: 7
Parameter: X 1... 7, number of unacknowledged packets.
Maximum number of unacknowledged info packets (I Frames) in a link, i.e.
MAXframe
defines the number of packets the PTC-IIex transmits continuously. The value should be
reduced in case of bad links.
9.6.18 MCon
Default setting: 0
Parameter: X 0... 6, frame type.
