Because I hate to do it on DOS/Win95/WinNT, I would like to solve the following problem on FreeBSD: I have to write a small programm that sends data to a serial port. The device on the serial port sends the data back (just like a loopback interface with TX/RX and RTS/CTS connected together). I need some advice or a pointer how to do this properly. I think I have to: 1. open /dev/cuaa0 2. set baudrate, bits, ... somehow (ioctl, termios, ???) 3. write/read to/from it within a select() loop 4. ??? Now I am looking for a small piece of source which contains the appropriate calls already so I don't have to think a lot. (Actually, I would like to figure it out by myself but the software has to be ready tomorrow evening, else I would have to do it on a Micro$oft OS :-). I already looked at the minicom sources but they are to complicated to understand them quickly... Thanks for any hints! -Andre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
