Asyn, asyn, and more asyn interpose interfaces

[Emmanuel Mayssat <emmanuel_mayssat@lynceantech.com>]

Hello all,

I am finally moving to asyn ;-)
I was wondering if there is a repository of asyn drivers that can be
found on the net. Any URL pointer?

Based on the modbus asyn driver already posted on tech-talk and the asyn
sources, I have started writing my own. I am currently working on one
for a radiation detector.

But here are some questions:

What are interpose interfaces? Could you give a simple example?

One of my asyn drivers is used to communicate with a serial device
(kudos to Jinhu Song for writing it). That serial device is powered over
the serial cable. So making it work requires some ioctl (to raise DTR
wire ). Now I would like to use an ethernet to serial converter. That
converter doesn't get the ioctl of course, but those commands needs to
be turned into telnet command. Obviously the required telnet commands
are function of the SoE converter.
Should I use an interpose interface to convert the ioctls into telnet
commands?
