PK-900 Gateway Option Supplement 10
L(isten) Your Gateway is placed in PACTOR-Listen mode. If the
ARXTOR
command is
ON
, it will also monitor AMTOR FEC and ARQ. If in
doubt, use the
PORT
command to see which mode is being copied.
S(end) The Gateway is placed in
PTSEND
. Transmission ends when the user
sends “=”.
AMTOR (in) / Packet (out)
With
XGATEWAY OFF
, your TNC accepts AMTOR calls to your
MYSELCAL
as normal
AMTOR link-ups. With
XGATEWAY ON
, an AMTOR call to your
MYSELCAL
results in
access to the Gateway and packet on Port 2. (The callsign in
MYGATE
plays no part in
Gateway access from AMTOR.)
The AMTOR Maildrop has priority over the AMTOR gateway function—this means
that with
TMAIL ON
, a station linking to your
MYSELCAL
can access your Maildrop.
However, the AMTOR user may type the new Maildrop command (“G”) to access the
Gateway—this surrenders the Maildrop to possible access by other users. There is no
command in the Gateway to return to the Maildrop.
If a packet user is already connected to your Gateway on Port 2 and has issued the
PORT 1
command to access AMTOR, the Gateway detects AMTOR calls only to the
packet user’s selcall, not your
MYSELCAL
.
There is no
PORT
command for AMTOR access. The AMTOR user is given access to
packet on Port 2, automatically.
An AMTOR station linked to the Gateway command processor doesn’t need to send
“+?” to let the Gateway transmit. The Gateway detects the
(RETURN)
at the end of the
line, seizes the link to give the command response, and then gives transmission back
to the user by ending the transmission with “+?”.
Once a packet connection has been established on Port 2, the Gateway seizes the
AMTOR link on Port 1 only when it has data to send to the user, it then gives the link
back by ending the transmission with “+?”.
Here is what an AMTOR user sees when connecting to your Gateway:
cmd:
ARQ NNML
+++ N7ML GATEWAY. TYPE ? FOR HELP.
+++ ENTER YOUR CALLSIGN: +?
KB7B
+++ You are on PORT 2, 1200 BPS PACKET. YOUR ID IS KB7B-15.
KB7B DE N7ML-7 GA+?
One way to establish a packet connection is to call a station directly:
J
18:30:56 P2 N7BCD
KB7B DE N7ML-7 GA+?
C N7BCD STAY
+++ CONNECTED TO N7BCD AT N7ML-7
