- I own a DeskPorte Fast V.34 and sell the 28.8P to budget-minded customers.
- We've had nothing but great results, and the one I own I chose from about
- eight for its ability to connect reliably and at high speed to various
- ISPs here in Portland (OR).
-
- There is a Huge document you can download from Microcom listing almost
- (yeah, I know...) all the commands for both models--it's a fairly unified
- command set.
-
- But . . . here is a setup string I highly recommend for Macs:
-
- *************
- Modem = Microcom DeskPorte Fast V.34, firmware rev. 3.3 (latest).
-
- Init string = AT&FEL1 &D%U2\N6\V4 :T73=160 :T42=0 S11=65 S0=0 <return>
-
- &F - get the factory defaults as a starting point.
- E - turn off command echo. (My choice. Your needs may differ.)
- L1 - Turn down the speaker!
- ( Or . . . L3 - adjust speaker volume to loud. I've put 27-ohm resistor in
- series with $#^@& speaker to shut up the %&$#*!! clicks and pops.)
- &D - ignore DTR (**necessary** for Macintosh).
- %U2 - unlocks serial-port speed so it follows first AT command.
- \N6 - sets LAPM reliable mode, fallback to MNP (full negotiation).
- \V4 - sends long-form result codes back to computer.
- :T73=160 - enables reporting of both send and receive speeds.
- Example: 24000/26400. (This is sure hidden from the user!)
- :T42=0 - sets V.34 connection speed relative to line quality.
- Zero is default (neither conservative nor aggressive).
- S11=65 - speeds up tone dialing
- S0=0 - sets auto-answer to off.
- ***********
- I have a second number for my modem line that has a custom ring: a briedf
- double-ring instead of single, long ring. So I also add:
- :T49=2 :T50=2
- ************
- If you have a 28.8P, the strings works fine, but the commands for
- sustom-ring are different. (I don't know what they are. The Microcom spec
- sheet *says* it is a feature . . .)
- ************
- Finally, you can lock in the above settings with
- AT*W <return>
- Then a simple ATZ <return> will set up the modem if it gets screwed up.
-
- Hope this helps. Let me know . . .
