I don't have hardware for it either. From looking at it an entry like
this in dev/puc/pucdata.c should get the card working:
{ "Cronyx Omega-PCI Serial Adapter",
{ 0x10b5, 0xc001, 0, 0 },
{ 0xffff, 0xffff, 0, 0 },
{
{ PUC_PORT_TYPE_COM, 0x18, 0x00, COM_FREQ },
{ PUC_PORT_TYPE_COM, 0x18, 0x08, COM_FREQ },
{ PUC_PORT_TYPE_COM, 0x18, 0x10, COM_FREQ },
{ PUC_PORT_TYPE_COM, 0x18, 0x18, COM_FREQ },
{ PUC_PORT_TYPE_COM, 0x18, 0x20, COM_FREQ },
{ PUC_PORT_TYPE_COM, 0x18, 0x28, COM_FREQ },
{ PUC_PORT_TYPE_COM, 0x18, 0x30, COM_FREQ },
{ PUC_PORT_TYPE_COM, 0x18, 0x38, COM_FREQ },
},
},
What the patch does do and this wouldn't is adding support for the
64 deep fifos and the hardware cts/rts. Maybe I should add a flags
field to the puc_device_description structure so that these things
can be set in there. I see that the top byte in the sio flags field
can be used to set the fifo size. I don't see that documented in
the sio man page though. Maybe the 16650A-type bit in the sio flags
will do the hardware cts/rts thing?
