AW: AW: AW: Serial port interface on frame grabber

[James Cameron]

I'm maintainer of PPTP, and I know PPP very well.

Yes, it would give you an IP transport across the serial link.

There's some additional overhead; encoding, and packet headers.  Yes,
you will lose some bandwidth.

Some pppd options can be used to reduce some of the overhead.  See man
pppd.

To compensate, you should work hard on yohur design to increase the
baud rate yet ensure the electrical signal has the right edges over
the transmission distance and cabling you are planning.

So what distance are you planning?

Is it 3.3V or 5V TTL serial, or conventional +/- 12V?  These days,
3.3V TTL level is more normal.  Very limited range without signal
conditioning and line drivers; of the order 50cm in a clean
environment, and much less in a noisy environment or bad grounding.
