Null Modem

[Fiz]

I have a PC with desigo insight on a pc with no external
net connection so dial in with remote access.

It connects through a serial null modem to system

it has started coming up with dp not connecting(baudrate?)

The comp to comp is set to 9600 and the dips on the board are set to
9600. can dial in ok but can't connect with null modem.

Any help would be appriciated

Is it a null modem cable? There is a difference.

[Fiz]

everything has been working.
and correct cable used.

Have removed and reinstalled cable computer to computer
on com1.same error

Is you computer com captured by another program that might be running. I had this happen with Cariier Comfort Link when trying to connect to a McQuay chiller. It had my port captured.

[Fiz]

Don't think so.

Only thing done was a incoming connection in network settings
to com3 from modem.

com1 not touched.

removed com1 the let it reinstall then created cable connecton
all looks fine.cable connection sees com1 if there. When
captured but somthing else it gives error. create two cable connections to
see what would happen if com1 captured and it tells you it
is in use.

It all looks fine just comes up with error.
doing my head in.

insite's connecton to it is simple to set up.
In config you go to communication and use steafa port and cable connection
No complicated setting.

Unless I missed something. But these hadn''t been touch prior to error. and only need to reselect cable connection when removed from modem config

aaaaahhhhh

flow set to hardware
needs setting to none

and although null modem set up in communication
not setup in modems.

not onsite but going to change
