Hi I design a modem using the TCM3105 (datasheet available on the net).
The computer device that will be connected to it has an RS-232 with only 1200 baud RX and 1200 baud TX half duplex.
1. What will happen if I configure the tcm3105 for 600RX/600TX whereas I am trying to send and receive data to it from the computer at 1200?
On sending, will the modem throw away sent characters because it can't cope?
On receiving, will the modem work ok, since it receives only 600 baud but it is configured for 1200. Or it could not cope with it at all?
2. Will the tcm3105 matter if it is connected to the RS232 port (+/- voltages available) or does it need 0v/5v for logic?
Thanks
