This value is device dependent.Port Generic Default Value0 (zero)Port Specific Override ValueRefer to SCF//DESC/config.des (Figure 3-3).Available ValuesDevice input values are defined in the header file, scf.h, and in Table3-14.Table 3-14 v_pollout Available ValuesDescription Macro EditModInterrupt driven IRQDRIVEN 0x0000Polled POLLED 0x0001212 OS-9 Device Descriptor and Configuration Module Reference
