(religious mode on - I know some people are just as religious about "ease of use" as I am about "being standard". That's why they make source code you can build your own from :-) )
Because IMHO it's the de-facto standard UUCP implementation at this time. There are thousands of sites with experienced admins & there are many places you can get incredibly good information concerning the HDB setup.
Moreover, if you know what HDB is, you shouldn't be reading this HOWTO :-)
Use the uuconv utility in /usr/sbin to convert config files from one mode to another.
If you use a "Direct" device in the Devices file, there's now a 10 second timeout compiled in. Make the name of the Device anything other than "Direct". If you tweak the example /etc/uucp files provided, you won't have problems with this one.
If you get chat script timeouts, you can tweak the sources by editing at line 323 in uuconf/syssub.c & changing the default timeouts from 10 seconds to something larger.
If you get chat script timeouts, typically connecting to other Taylor sites, a pause after login can fix this.

Some kernels experience modems hanging up after a couple of seconds. The following patch sent by Ian Taylor might help.
*** conn.c.orig Mon Feb 22 20:25:24 1993 --- conn.c Mon Feb 22 20:33:10 1993 *************** *** 204,209 **** --- 204,212 ---- /* Make sure any signal reporting has been done before we set fLog_sighup back to TRUE. */ + /* SMR: it seems to me if we don't care about SIGHUPS, we should clear + the flag before we return */ + afSignal[INDEXSIG_SIGHUP] = FALSE; ulog (LOG_ERROR, (const char *) NULL); fLog_sighup = TRUE;
Taylor in HDB mode seems to be sensitive to white space & blank lines. To be safe, make sure that there are no blank lines or trailing spaces in the Permissions file.
Lastly, make sure that you have a file called remote.unknown in /usr/lib/uucp or /etc/uucp & that it's *NOT* executable.
See the O'Reilly & Associates book "Managing UUCP & USENET" for details regarding this file.
In all probability, you are attempting to use a dialer that doesn't exist, or the dialer you've specified in the port files doesn't match up with any valid devices in the dial file.
The following are "known-good" config files for Taylor 1.05 under Linux in HoneyDanBer mode. They work on kernels of 0.99-8 or later. All files should be in /usr/lib/uucp or /etc/uucp unless you've tweaked the sources to put the uucp library elsewhere.
If you *HAVE* put things in non-standard places, be aware that things like sendmail might get very confused. You need to ensure that all communications-related programs agree on your idea of "standard" paths.

The new v1.05 has an added '-z' switch to uucico that will try alternate numbers for a remote system.
You can else use Taylor mode & "systemyouarecalling-2" (see "sys" in config. files section for more details)
