This morning, around 19:00 UTC, 14 MAR 84, Randy VE1SAT/VE6(VE1PAC) and
I did some more gateway experiments.  Randy was able to remotely command a
local LA two meter TNC.  I had two TAPR TNCs placed back to back on
their serial ports, with one TNC connected to the ao-10 gear, and the other
connected to a 2 meter handheld on 145.36MHz.

The oscar TNC was in transparent mode, the local TNC was just attached,
initially it was in command mode.  The setup was

    VE1SAT - remote satellite station/TNC
		    |
		    v
	   Oscar-10 Transponder
		    |
		    v
 NK6K-0 satellite packet station, Redondo Beach
		    |
		    v
    NK6K-0 local packet station (145.36 MHz)
		    |
		    v
	     Los Angles/San Diego

Once VE1SAT was connected to the serial input of a local LA TNC, he could
connect to anyone.  The endpoint selected was WB6YMH-2, a TNC with a
CPM ($50 820 board) system.  Once connected to WB6YMH-2, Randy ran a
version of the W3IWI orbit program.

The test ended when the temporary cable between TNCs fell apart, but
it was enough to show the idea.
