Description Brian Trang 2001-10-03 19:50:00 UTC

To all,

I have a sentry unit, a serial console server that is connected to
both linux and freebsd server.  When I connect to the console
of the linux server, everything works fine.  But when I connect
to the console of the freebsd server, the connect disconnect
immediately right after I hit <Enter>.  I look at the log of the
sentry unit and it shows Framing Error.

I follow the pinout of the null modem and all are setup correctly.

I search around the web for resources, notice that the
console of freebsd requires CTS/RTS handshake for connection
over 2400baud.

Does anyone know how to disable CTS/RTS on the freebsd
since the sentry commander do not requre CTS/RTS?

I have tried modifying the gettytab, ttys and rc.serial files, but
nothing seems to work.  I also have tried modifying the stty
setting, but nothing works.

Does anyone know how to setup the serial console ttyd0
so that 9600 baud only require DSR/DTR, TD/RD and Ground?
(and disable CTS/RTS).  The setry unit do not have CTS/RTS
handshake support.

My email address is briant@bayarea.net if email is possible.

Thanks for the help.

Brian T.

Please send this information to freebsd-questions@freebsd.org. 

FYI, the only thing you need for a serial console on freebsd for speeds 
up to 38,400 are tx, rx, and ground. I suspect you're having other problems.
