- 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,
-

-
- 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
