Eli: Thanks for the reply :-) >I don't know anything about how Perl implements the functions you are >trying to use (e.g., what exactly does `sysopen' do).

OK I'll add it to the list of things to try :-) >Btw, why did you need O_EXCL? I've done C/C++ serial stuff under Win32, and the API docs recommend opening the serial port in exclusive mode to avoid the confusion of two processes/ threads trying to use one port at the same time. I just assumed that the same principal applied to DOS. Am I missing something here? BTW Perl -V indicates "djgpp v2 port (perl5004) by Laszlo Molnar, 1997". Do you know which newsgroup(s) he Laszlo hangs out on? David Christensen dchrist AT dnai DOT com
