HELLO
HI, NAME IS WALT ...
The other way is to call CQ in Unproto mode and wait for a response:
S
+++ SENDING. TO END, TYPE ’=’.
+?
CQ DE KB7B-15 FROM AMTOR=
KB7B DE N7ML-7 GA+?
+++ CONNECTED TO N7BCD AT N7ML-7
+?
HI, NAME IS WALT. WHAT DO YOU MEAN BY “FROM AMTOR”?
HELLO ...
One thing to keep in mind when accessing VHF packet from AMTOR is that the data
rates on the two radio ports are widely different. In reading a long message from a
packet BBS, the BBS sends the entire message to the Gateway packet port, then may
time out and disconnect before the message has completed transmission on the
AMTOR port. (The Gateway buffers the data so none of the message is lost.)
However, on the packet side, the BBS has wasted time waiting for the next command,
preventing other stations from using the BBS.
L(isten) Port 2 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). Some
TNC monitoring characters are translated for AMTOR:
L
+++ LISTENING ON
KB7B DE N7ML-7 GA+?
P2 N7BCD)W1AW (C)
P2 N7BCD)W1AW (D)
+?
L
+++ LISTENING OFF
KB7B DE N7ML-7 GA+?
S(end) The Gateway sends UI frames with a destination of “CQ”. The source
field is the user’s callsign with the SSID decremented by one. The
Gateway holds the data characters until the user sends a (RETURN),
whereupon the held data is broadcast.
PACTOR (in) / Packet (out)
With XGATEWAY OFF, your TNC accepts PACTOR calls to your MYPTCALL as a normal
PACTOR link-up. With XGATEWAY ON, a PACTOR call to your MYPTCALL results in
access to the Gateway and therefore, packet mode on Port 2. (Your MYGATE call plays
no part in Gateway access from PACTOR.)
