The devc-par manager is a parallel port manager for QNX Neutrino. It can support up to 4 parallel ports.
The devc-par driver polls the hardware to detect if a character has been sent.
If you don't specify any ports (using the -p or -b options), devc-par tries to interrogate the BIOS area to determine the number of parallel ports detected by the BIOS. If no ports are found, devc-par silently exits.
You can use the -p option to override the use of the BIOS data area (at 0040:0008).
The only translation of output is the mapping of a newline character to a CR/LF if the OPOST flag is set.
Reading from devc-par works the same as reading from /dev/null.
Start devc-par, defaulting for all parallel ports found by the BIOS:
devc-par &
Start devc-par with only the first parallel port:
devc-par -p 0x3f8 &
Or:
devc-par -b 1 &
