Hi, For my C# program to work as a serial port interface, I need to send "ENQ" and expect back "ACK". From what i understood in replies to my earlier questions in this forum, i think the system expects me to send '5' and give back a '6' (ASCII equivalents of ENQ and ACK). So instead of sending a string which is "ENQ", i can send a ch...
Hello, I'm working with a GPS module that is transferring data to my mac over a serial RS232-to-USB interface. I've written a objC program that takes the raw data and converts it into meaningful information. Using a program called goSerial, I'm able to log all incoming data into a text file.

The device & PC talk briefly, then seem to loose the dialogue, and then get it again...

Does java's javax.comm library support "9-bit" serial communication? (use of parity bit or "address bit" as an out-of-band signaling mechanism for framing information) Does the win32 communications API support it?

Hi, I have plugged in a RS-232 cable to my PC to do a C# program to read from the port.
