HDLC synchronous

HDLC synchronous

[Antonio Di Bacco]

I had a look to hdlc_enet.c in 8xx_io and it seems to me that it only supports 
asynchronous HDLC (speaks about cts rts). Is this true?

Bye,
Antonio.

I 've understood well,  the hdlc_enet.c driver provided in denk kernel works 
if the hdlc controller can use cts and rts but my board has only INPUT, 
OUTPUT, CLK_INPUT and CLOCK_OUPUT pins. I imagine this is a synchronous 
interface, isn't it?

Bye,
Antonio.

Our hdlc_enet.c driver is a custom driver that is designed to work in
a pretty specific environment. You can use it as a model for your own
implementation, but unless you understand exactly what it's doing you
better be careful.

No, I'm not going to explain it. If you  can't  figure  it  out,  you
didn't want to know anyway... :-)
