One sort of neat feature that the sales brochure on the Telebit modems didn't point out is that the Trailblazer version 3.x and Trailblazer Plus can be programmed to attack dial from the non volitile directory until they get a connection. I don't know about the T-1000, it might have this feature too, but I don't have the book for the T-1000 here. The modem can also be set to automatically attack dial if the carrier is dropped. These features are real handy if you're using a trailblazer in a dial-up link that suffers from either power or phone glitches. The Trailblazer Plus also has an interface that can be programmed for bisync operation in an IBM environment. I also like the fact that the Trailblazer uses an EEPROM for setting storage, rather than a battery backed RAM. It seems like the batteries on the RAM in other modems go dead just about the time the modem experiences a power outage. I also like the HST 9624, but I have to give the nod to the Trailblzers for overall quality and clean interior construction. --Bill

Very interesting... I hadn't noticed this feature in my perusal of the Trailblazer Plus manuals, and a quick re-check doesn't spot anthting. How are these features invoked? My TT+ wish-list is for a speed selection on pulse dialling, and a more robust &R1 command, that is queued instead of flushing the buffers. How the hell is my script supposed to know the buffers are empty and it's safe to diddle compression again? -- -Colin (uunet!microsof!w-colinp)

Page 4-29 of the 90048-01 Rev.A "Commands and Registers Reference Manual" for the Trailblazer Plus says that automatic redial is accomplished with S103. It looks like option 2 is the one: "2 Enable automatic dialing whenever the modem is on-hook and the DTR control signal is active. This option allows the modem to automatically attempt to re-establish a dropped connection without operation intervention which is useful when the local DTE behaves as if it were connected to a dedicated line. ... In each of the above cases, the modem will attempt to connect in either originate or answer mode depending on the setting of the S100 register. For modems which have front panel switches, the number dialed is dependent on the setting of the A/B switch when the dialing function is initiated. If the A/B switch is in the A position the first number (N0) in the Number Directory is dialed; whereas if the switch is in the B position the second number (N1) is dialed. If you modem does not have front panel switches, it will dial the first number in the Number Directory when the auto-dial is initiated via the DTR signal as described for options 1 and 2." S101 is probably the register for you if you are running the trailblazers on a leased line. Option 1 attempts a connect in answer mode every 20 seconds whenever a carrier is NOT present. Option 2 attempts to connect in originate mode every 20 seconds if a carrier is not present. You'd need to remember to set S103 back to option 0 after you finish your call. Uucico would need minor hacking if you were running a uugetty on the line to make sure that the S103 was at option 0. I'm not exactly sure what to do about the potentially indeterminate start-up delay if you didn't have HDB source for hacking. In Xenix you could hanle it nicely in your dialer.c script. I suppose with HDB, you could do your dialing inside your own c program and then fork uuccico and wait for uucico to finish, then go ahead and kill the modem. By the way, I use a bunch of /d (22 to be exact) in my dialer expect-send string when attempting a PEP answer last connect. We have ESS-4 (apparently) here, and even long distance calls seem to make it in 40 sec (including the answer handshake). That gives us 4 seconds to spare. Season to tase for crossbar or step-by-step (yuck!) offices. --Bill

Except it's S104. You scared me there. I have the same rev. but I
looked at S103, and it was "Rackmount Controller Exclusive Access".
Checked the rev. again. Same. Checked your page reference, and
came up with S104, which is as you described.

One of the features I most miss from the Racal-Vadic's I used to use is the ability to attack dial from ANY of the numbers in in nvRAM. They had a feature called "linking" which, if a given connect sequence failed, would go to a number. This gave many possibilities such as: #1 number. If fail goto #1 (Attack one number till success) #2 number. If fail goto #4 (Attack on 2 numbers till success) #3 number. If fail goto #5 (Try 2 numbers then quit) #4 number. If fail goto #2 #5 number I also wish: 1)There was a way to store more numbers in the modems. I carry one of my TB+ modems to whatever machine I am working on at the time and, with all of the switch settings I need to do to contact certain machines (yes, you CAN do ATN0=S51=5S111=30DT555-1212\Info), it would be nice to be able to store about 20-30 numbers. I suspect that there is no H/W limit to 10 numbers, just that 20 numbers would scroll off a 24 line screen. 2)There was documentation on all switch settings. Even a usenet posting would be OK (although an errata sheet would be preferred). Things like S51=254 and S120=packet delay and whatever else has not been documented. I suspect that every unlisted register does SOMETHING but have been reluctant to try setting them to random values. 3)There was a way to select A/B configurations by using an S register. This would let those of us with the grey model use dual configurations. Although I have these minor complaints, I love my modems and have been responsible for the sale of at least 30 more of them around the country (several NOT on the 1/2 price deal). For the moment, they are the best way to push large amounts of data around if you can rely on one on the other end of the phone line and they spoof the protocol you use. /\/\ \/\/ -- Michael R.

It looks like option 2 is the one: That should be S104, not 103. The page is correct. Thanks for the information! I've read the manual I-don't-know-how-many times, and I never saw that. I have found the memory dumper/modifier hidden behind ATJ, though... anyone else hacked the modem? -- -Colin (uunet!microsof!w-colinp)
