Comark "Desktalk II" modem is 2400BPS,Fully Hayes Compat.,sync or async,error correction optional(both modems must have it to work), and has 5 year warranty. It is also upgradable to 4800 BPS. This involves sending it back so they can install & test a chip. The 5 year warranty also restarts. Works great! Comark 2400BPS modem - $159.- 135 N. Brandon Drive 4800BPS modem - $399.- Glendale Hts. IL. 60139 4800BPS upgrade-$199.- (312) 351-9700

I'm also using a Desktalk II. It's worked satisfactorily for a couple of weeks now. More comments: The 2400bps external version is now $149, down from the earlier $159 (Internal version is less.) The MNP level-4 (2400bps ext.) version is currently $229. (I don't know about the 4800bps units.) A male-to-female rs232 cable is needed; Comark will sell you one for $12. Features: "fully compatible" with Hayes AT commands & register set. Bell 103/212, CCIT V.22/V.22bis internal speaker with software volume control line jack and phone jack on unit external power supply lotsa "Power-On" LEDs, labelled HS,AA,RI,OH,CD,TD,RD,RTS,CTS,DTR,DSR and they blink engagingly when I type (:-) :-) :-) some sort of terminal emulator for MS-DOS -- seems to work, ohboy... company spells "compatible" correctly Massive heat sink on a power transistor inside. Leaving clearance for this sink seems to account for most of the external's size Overall, I'm happy (==satisfied) with it, enough that I'm about ready to sell my old reliable USR Password finally. I kind of wish I'd gotten the MNP version; I heard a rumor that you can upgrade to this, but the manual says nothing about this. In contrast, it does make passing mention of an upgrade to 4800bps. I had to ask them for a warranty card, which wasn't packed (and which I haven't sent back in yet, now that I think of it...) -- bob,mon (bobmon@iuvax.cs.indiana.edu) "`This must be deep' means `I can recognize all these words individually, but dam' if I can make any sense out of the order in which they currently appear....'" - Gil Scott Herron

According to the people I talked to at Incomm Data who build the modem the 4800 is a 2400 with MNP compression (Level-5?) to get double speed > > Features: > "fully compatible" with Hayes AT commands & register set. > Bell 103/212, CCIT V.22/V.22bis > internal speaker with software volume control The speaker is a tiny one and distorts badly the dial tone and dialing if you turn it up to here call progress. I just set it low and let the modem do the work. > > Overall, I'm happy (==satisfied) with it, enough that I'm about ready to sell > my old reliable USR Password finally.

They did imply an addon card to support 4800. Since I got my first one I got 12 more for work to use for uucp. Not as nice as a Telebit but far less money. I haven't had any problem using it for both inbound and outbound uucp on the same line under Xenix. It does save the speed you used to set the modem up with so that an ATZ or DTR toggle will put the modem back where you want it. Watch out for some uucico's tho because it does need about .5 sec after a CR to execute before it will take the next command. (Attention Apollo users: I have patched uucico to work with the modem under DOMAIN/IX 9.5 - SR10 HDB works great out of the box. send e-mail for the 9.5 executables) I belive the 4.2BSD uucico dialers also have this type of problem because they send CR ATD # CR. I don't know what extra you get if you buy the Incomm name. The best price has to be from Comark / USAFLEX in Glendale Hts, Il. Steve Piette Regional Systems Engineer Apollo Computer Inc.
