How to view the contents od a device file ??

Hi,

Is there any tool/way to view the contenta of a device file like /dev/tty0p7 ?
Let me give some background of our problem. We are trying to pass some serial data from one hpux m/c to another through a device. We are not able to see any data on the destination m/c. For this, we want to check wheather any data is received by the device file of the source m/c.
Any help/pointer is highly appreciated.

Thanks & Regards,
Ramesh.K.R.

Ramesh,

Did you try a simple 'cat < /dev/tty0p7' ? It should work.

I think this is a case for netfmt (see man netfmt). This will log all packets in and out of your server. It will produce a huge logfile so dont run for too long, the trick is to filter out only what you want (by ip, user, tty).
Im from Palmerston North, New Zealand, but somehow ended up in London...
