ct ver8.53 -loop

Questions on CT single port link

We have been testing the "-LOOP/loop" option for the single
port notebook computer link for the KH0AM M/M operation.

We tested the "-LOOP" option with v8.47 & 8.53.
(CT V9 is not available in Japan yet)
The configuration was as follows;

	+-------<-----------<-------+
	|                           |
	|   +--->---+   +--->---+   |
	|   |       |   |       |   |
       RxD TxD     RxD TxD     RxD TxD　<--- 9pin com1
     ----------- ----------  ----------
     | J3100   | | J3100  |  | J3100  |  J3100 is mostly same
     |   SS001 | |   SX   |  |    GS  |  as T3*** by Toshiba.
     ----------- ----------  ---------
	 No.3       No.1        No.2    <--- station number
GND were connected.

CT's setup was ; 
wwcw,multi-multi,tnc-none,cwport-lpt1,network -com1-9600baud

Result;
Entered QSO data was transfered to the next computer, but it
was not transfered any more.
This means that the data from No.1 -> No.2, No.2 -> No.3, 
No.3 -> No.2 were transfered but not relayed (#1 -> #2) -> #3
and so on. There were no differences between with "-loop" or
without "-loop" option.

We change the settings like "-loop" or "-LOOP", baud rate
9600bps to 1200bps etc but could not make any differences.

Does anyone suggest me what was wrong?
I will summerise the answers later.

If this -LOOP option does not work, we have to hire SIX 2port
notebook computers.... Nealy impossible!

Thanks in advance
