A full nullmodem will either run DTR from the terminal to DCD at the computer, or loop DTR on the computer back to DCD on the computer. You can tell the SOFTWARE to ignore DCD by setting the CLOCAL flag in the terminal driver. edit the file /etc/gettydefs and add the word CLOCAL to the flags in the second and third sections of the line corresponding to your terminal. In fact, my copy of gettydefs contains a comment telling you to do this. Also, it is definitely mentioned in the linux HOWTO document concerning serial ports and terminals. Check /usr/doc/faq for the HOWTO documents (if you installed them), otherwise look here: http://www.ssc.com/linux/howto.html Chris. - -- Christopher Biggs -- chris@stallion.oz.au - Ph+61-7-3270-4266 - PGP & MIME OK There's a bug in my mailer that mangles my sig but V guvax V'ir svkrq vg abj.
