# sergensio(5)

How to use a serial gensio

## NAME

sergensio - How to use a serial gensio

## DESCRIPTION

**NOTE:** sergensio is deprecated, the functionality for it is not done with the **acontrol()** and **control()** functions in the main gensio type.

A **sergensio** object is a type of gensio that provides serial port functions.  It cannot be directly created, instead you create a gensio that has serial port capabilities and cast it using the **gensio\_to\_sergensio()** function.

A **sergensio** object may be a client, meaning that you can set serial port parameters for that gensio.  This is what you would normally expect, and works for all serial port types.

A **sergensio** object may also be a server, meaning that it can receive requests from the remote end to set serial port parameters.  Currently only the **telnet** gensio has server capability, so a remote end may request that serial port parameters be set.
