HDLC and X.25 on Sun Fire-Wire 440 serial port B

Post by Nick the Amateur LARTi » Wed, 22 Sep 2004 23:05:57



I am looking for information on how to configure the serial port B
(ttyb) on a Sun Fire-Wire 440 with Solaris 9 and Solstice X25 9.2 for
an X25 link. I have't found anything in the online documentation on
the www.sun.com website. What I have found out on that machine is that
there is no HDLC driver installed.

You can't -- the serial ports in v440 are driven by a 16550A
equivalent type UART, which can't work in synchronous mode.
You will need an HDLC board.

In general, if the port if driven by the su driver (for 16550
look-a-like chips), it can't do sychronous mode working.
If the port if driven by the se driver (for 82532 look-a-like
chips), it should be able to do sychronous mode working.

I don't think you can, since the serial port lacks clock pins.

1. Fire-wire Card For Linux

I have a Sony DCR-TRV530 that has an iLinkT (IEEE 1394) DV Interface. I am
looking for a fire-wire card that will work with my camcorder to do video
capture and I am wondering which cards will work with Linux.
Any help would be appreciated.
Thanks!
John
