silence mode in rs232/rs484

[AliBahar]

Hi
I want to Force the output of typical uC to silence mode in case of using rs232 or rs484.
by the way I want to do it by creating C code in the typical compiler.
any suggestion?

"silence mode" means what?

"silence mode" means what?

the conditions which controller is forced to do nothing except monitoring the bus.
the same as Listen Only mode.

If you could explain what exactly is to be implemented, the solution seems easy,
please describe in detail what exactly is needed.

in Listen Only mode the slave just monitors the bus and doesn't make response to request of masters except restart.
so in this case the slave becomes idle.
I want to know how I can implement this mode if the controllers communicate with each other using rs232.
by the way I have significant restriction. my code must be supported by all c compilers.
so I am not permitted to use any specific peripheral's configuration methods

Why don´t you avoid the serial interruption treatment simply using an if command to skip the received packs ? The overhead due to the interruption itself is negligible even at the fastest baud rate, if compared to the processing capacity of the uC.
