Hi,
first of all let me congratulate the Jolitz and everybody who
made 386BSD possible. Thanks also to Amancio who helped me with the
X system.
However, there are still two major problems I haven't been
able to solve:
1) lp driver: I installed the one by Tibor Sashegyi from agate. It seems
to be very fast but it doesn't print correctly some large files (for
example, files produced by ghostscript). I read in this
newsgroup that some motherboards are not able to correctly respond to
interrupts and decided to try the only driver I found which does not
use interrupts. This new one works fine (thanks to Andy Valencia) but
seems to be very slow. The speed I get from DOS (arghh :-) ) or
Interactive Unix is 6 or 7 times faster. That means that when I have to
print a large document, it pays to reboot DOS only to do the printing
and then come back to BSD. Any idea what is wrong ??
2)SLIP (or com driver): I connected my box at home to a Sun machine in
my university through a leased line (awfully expensive here in Brasil
:-( and bought two V.32bis modems. The connection works but every now
and then I get the famous "SILO OVERFLOW" message. I have Chris'
multiserial driver installed but even at low speeds (1200 or 2400), I
still get the messages. I don't care about the messages but the
problem is that the slip connection sometimes hang in the middle of a
file transfer. I have read that a 16550 would help but:
1) I think my internal modem doesn't have a 16550 (it is a
TurboModem V.32bis).
2) File transfers work perfectly all right under DOS. Ok Ok, I
know that DOS is not a multitasking system but I just tested it under
Interactive without any problems. In fact, the speed under Interactive
is higher than in BSD (0.86 kbytes per second against 0.8, with 9600
and no compression).
Oh, I have the patchkit installed, though I had to delete a "return;"
statement in patch 19 that prevented slip from working. What is wrong?
HELPPP!
Any help VERY appreciated,
Carlos Ruggiero (toto@uspfsc.ifqsc.usp.br or usp@jif.berkeley.edu)
PS: The Sun I'm connected to is a Sparcstation 1+. I know this is not
the right place to ask this but... Has anyone got SLIP running at
14400 on a Sparcstation 1+?When I try to set the serial to 19200 (a
SPC/S board), there is no way to implement flow control and file
transfers become very inefficient
