Conform enuntului trebuie implementat un driver pentru
UART16550. Varianta 16550 dispune de un buffer intern de 16 bytes, dar care
nu este functional. Variantele 16550A si 16650 dispun de buffere interne
functionale de 16, respectiv 32 de bytes. In masina virtuala linux porturile
seriale sunt recunoscute ca UART16550A.
Driverul nostru trebuie sa inhibe folosirea bufferelor interne disponibile
pe 16550A (dar care nu sunt functionale pe 16550 pt care ar trebui sa fie
driverul) ?
