Hi,

I have a requirement for implementing a virtual com port type device
where it just looks like the normal /dev/cuaa* but when any program
(such as ppp, seyon, kermit etc) opens it, it will connect to a
remote machine actual physical com port. 

What is the best way of doing it ? Creating the device special file
similarly to /dev/cuaa* and write a background daemon that opens the
port and does a select() on that port ?

I may have to be able to add many such devices for testing purpose.

Any ideas/suggestions appreciated.

Thanks in advance.
