PK-900 Gateway Option Supplement
8
PORT 1 to initiate a cross-port connection. Typing “Port” by itself
shows the current value of PORT, the operating mode on that port, and
the user’s ID to be used on that port. Port 1 AMTOR and PACTOR
users can only access Port 2 (packet), so the PORT command isn’t
implemented for them.
L(isten) None of the Gateway’s local commands affect monitoring—packet
frames are shown to the user as if MONITOR and MCON were set to a
value of 4 (UI, I, C, D, UA and DM frames). Other than that,
monitoring behaves as if all other commands were set to their default
values (no MPROTO, etc.).
SEND The Gateway sends UI frames with a destination of “CQ.” The source
field is the user’s callsign with the SSID decremented by one.
Packet (in) / AMTOR (out)
Here’s what a Port 2 packet user (KB7B) would see if accessing the AMTOR mode
through Port 1 of your Gateway (ex.: N7ML-7):
cmd:C N7ML-7
*** CONNECTED to N7ML-7
+++ N7ML Gateway. Other port (1) is AMTOR. Type ? for help.
+++ You are on Port 2, 1200 bps Packet. Your ID is KB7B-15.
de N7ML-7 (B,C,D,J,L,N,P,S,?) >
p 1
+++ Cross Access to Port 1, AMTOR. Your ID is KKBB.
de N7ML-7 (B,C,D,J,L,N,P,S,?) >
At this point there are two ways for KB7B to establish an AMTOR link—the first is
to call a known station directly:
C NBCD
+++ CONNECTED to NBCD at N7ML-7
+++ Note: Over = “+?”, End = <CTRL-D>. You’re sending.
N7BCD DE KB7B - HELLO +?
HI THERE...
Keeping in mind that only one station can transmit at a time, the packet user must
end each transmission with +? (RETURN) to let the other station respond. Either
station may end the communication; if it’s KB7B, a (CTRL-D) packet frame tells the
Gateway to shut down the AMTOR link.
The other way to set up a link is to call CQ in AMTOR FEC and wait for an ARQ
response:
S
+++ Sending. To end, type ‘=’.
CQ CQ CQ DE KB7B SELCAL KKBB
CQ CQ CQ DE KB7B SELCAL KKBB K=
de N7ML-7 (B,C,D,J,L,N,P,S,?) >
