Hi,
I used to use Sernet V2.22, for connection of Q60 to QPC2. I configured
4 version of SERNET for each SERial port, SER1-SER4
I built a custom 4 port cable and connected Q60, QPC2, QXL, QL (with
SIMSER for split ports on SER1/2)
SERNET connection is a sort of Null Modem connection, on Q60/QPC2/QXL
using standard PC serial ports a standard commercial Null Modem cable
can be used.
But the main connections are: TX-RX, RTS-CTS, GND and all the
connections interchange with each SERNET stattion.
I did think about a SERNET interface box with all the SERNET connections
made inside the box and connection to each SERNET station with straight
cables. But alas, I never actually built if.
The problems arise with the QXL and QL whose serial ports are slower
than the Q60 & QPC2. But lower the Baud rate to the lowest common speed
gave reliable connections.
Note: Superhermes SER3 port is unsupported by Sernet due to the lack of
split port speeds. Maybe if the Superhermes SER3 source code was
available this could addressed.
