I have this same problem and have been unable to solve it. I suspect the
cause is noise picked up at the modem input. This causes a system crash
every few minutes on my dataengine. I've found if I remove the cable from
the 9600 modem, the problem diminishes. Johan has produced a real slick
product here; I wish I could get it to work!

I have been attempting to run jnos40 in my data engine. I use a 1200
baud modem in one side of the data engine and a 9600 baud modem
in the other side.
I seem to consistently get quite a few Brkints (break or abort
interupts) in the 9600 Baud port. "Quite a few" is about 100
per second. My impression is that the data engine is servicing
so many interupts, that it has no time to do much else. It is
related to the 9600 baud modem, cause if I take it out, I can
do not see this problem. My 9600 baud modem jumpers are set up
as default from Kantronics.
Questions
1) What actually causes the Brkint to happen.
2) Any ideas as to what I could try to fix this.
Thanks

I recall that some of the 9600 modems do not have the RX Data line
qualified by the DCD line. That can cause lots of interrupts when noise is
received as bad packets (probably a massive number of framing errors).
The solution is to modify the modem to use the DCD signal to gate RX Data.

Help JNOS <-> Phone modem
I am trying to setup a host running JNOS 1.10c connected to a lan. And I also
want to give phone access to the host via a Hayes compatible telephone modem.
To this moment, I haven't been able to run the phone modem properly with JNOS.
What I want is that a user can dial the JNOS telephone number and log into the
bbs as if he had issued a telnet command. Is it possible to do this? How? What
are the commands I must put into the autoexec.nos file?
Any kind of info will be appreciated.
