The communication link is a direct null modem, full duplex RS-232 connection with, 9600 baud, 7 data bits, Even Parity, and 1 Stop bit. Also need to assert both DTR and RTS at all times. Which one of the following is a better choise?
1) Use a RS-232 to ethernet converter (cable/hardware) and use MINA Socket communication. 2) Use MINA Serial communication classes to talk to the device directly. Can anyone provide an example of reading and writing to and from a com port and parsing messages over RS-232?

All values are from the ASCII character set. ) Fields are seperated by FS [0x1C] -- View this message in context: http://old.nabble.com/System-design-considerations-tp29966545p29986644.html Sent from the Apache MINA User Forum mailing list archive at Nabble.com.
