[REBOL] Re: ouverture port serie

From: dlhawley::attbi::com at: 9-Dec-2002 23:06

whether or not 2 programs can open the same serial portprobably depends on your operating system. Under POSIX (LINUX) like os, you may be able to open multiple times for write and maybe even read. This will depend on port permissions andany locking done by the first programto do an open. If you open 2x for read, then you may be surprised at what you see from each reader since data read by one will not be available to the other. Write data will also be intermixed depending on buffering between the two writers and the serial port driver. Dave G. Scott Jones wrote:
