I put NetBSD on a Compaq laptop. Works great! X and everything.
For some reason the PCMCIA can't see the 3COM network card (that is
supported in the Kernel) so I took the laptop over to another NetBSD machine
that has network support.
Using pppd and a null serial cable, I established a direct connect between
the machines. I has setup IPNAT on the server so the laptop has access to
the network/internet! At 115200bps the connection is quite tolerable. I
have BSD compression set at 15, for good compression, though setting to
anything else still results in pppd returning a compression rate of 15...
Initially I will get the error:
ppp_deflate0: exceeded mru (1508>1504)
Doesn't seem to cause any problems though.
When doing low data rate operations (telnet) it's okay. But when I download
a file via FTP I get the console error:
z_decompress0: inflate returned -3()
Lost compression sync: disabling compression
Now it still works, just BSD compression is now off and my max xfer rate is
~ 11.5K/sec
I'm not complaining, mind you, just curious as to why this happens.
Now if someone would hack pppd to work with the lpt port and a null parallel
cable...
