Dear Sirs,
I have connected one of the RS232 ports of my PC with FreeBSD (v6.3) on
it to a device that does not understand XON/XOFF flow control. I run the
tip program to connect to that device.
How do I configure tip and/or the serial port so that the FreeBSD PC
will NOT send XOFFs or XONs to the device?
When I run:
stty -a -f /dev/cuad0
where /dev/cuad0 is the device associated with the port, it outputs
(among other things):
iflags: ... ixon -ixoff ...
From my reading of the stty man page, I would think that means the port
is already configured to not send XOFFs.
Is there something I need to do to /etc/remote to tell tip to not enable
XON/XOFF?
Please respond to this email address as I do not subscribe to the

Hi Jeff,
I think there might be a problem with the man page for tip(1) on 6.x, as
an entry for 'tandem' was added to the tip sources about 2 years ago.
It's in the 7.x man page as you can see at:
http://www.freebsd.org/cgi/man.cgi?query=tipmanpath=FreeBSD+7.0-RELEASEformat=html
in 'Variables'. 'tandem' shows up in a variable listing (~v) in tip on a
6.x system I have here but I don't have an appropriate set up at hand to
verify that it operates correctly.
Let us know how you go with it. If it works for you then a PR would be
in order.

[1] Extract from the tip(1) man page on 7.x:
tandem (bool) Use XON/XOFF flow control to throttle data from the remote
host; abbreviated ta. The default value is true unless the nt
capability has been specified in /etc/remote, in which case the
default value is false.
