Hello. I have a need for a device to receive RS232 codes in and spit out a corresponding RS232 code on another port.
For example, if a control processor has been programmed to send RS232 codes to a tv, and the tv is swapped for another brand, I'd like to install this Arduino device on the control port connection for the original tv and then send the appropriate/new RS232 codes out of the other Arduino port for the new brand. In essence I would call it an RS232 translator. I know that the sensible approach would be to simply change the codes in the control processor for the new display but sometimes that isnt possible.
Ideally, RS232 code definition would be done over ethernet.

Is this at all possible?
You are confusing RS-232, which is the ELECTRICAL specification of the connection, with the data codes being sent/received, which are probably ASCII codes. The change from RS-232 voltages to TTL voltages used by an Arduino is done with an interface board.
To get your project going any further, you need to know what the exact message formats and codes being used to control the first TV and any other TV that may replace it.
You also need to determine the data rate or speed of the connection to the different TV devices.
