I haven't used Interactive yet, so I can't post any details.  Doesn't
the operating system come with default gettydefs entries for the various
speeds?  The default entries for 19200 or 38400 would be a good place to
start, usually the only thing that needs tweaking is hardware flow control.

The Dialers script may need to set different register settings for dialing
different sites, and whether you're making a uucp call or a cu call.

No single Dialers file script can meet all your needs.  The best thing to
do is call Telebit Tech Support.  Tech support can give you advice on which
register settings may be necessary for the different types of calls you're
going to make.  However, here are a few examples that may get you started.  
They assume you're using the &F3 or &F4 defaults:

# t16gen: General-purpose dialer script for use with cu.  This script sets
# XON/XOFF flow control in the modem and enables the +++ escape sequence.
t16gen  =W-,  "" ATE1X1S2=43S59=7S58=3S68=255\r\c OK ATDT\T\r\c CONNECT

# t16uu: General-purpose dialer script for use with uucp.  This script just
# makes the modem transparent to data.  Protocol support is not enabled.
t16uu  =W-,  "" ATX1S59=7S58=0\r\c OK ATDT\T\r\c CONNECT

# t16uucp: Special dialer script to enable UUCP protocol support.  Just in
# case protocol support is not negotiated, it makes the modem transparent.
t16uucp  =W-,  "" ATX1S59=7S58=0S111=30S180=3\r\c OK ATDT\T\r\c CONNECT

# t16noec: Special dialer script to disable error correction.  For use
# with hosts that don't have EC modems, and barf when an EC modem dials in.
t16noec  =W-,  "" ATX1S59=7S180=0\r\c OK ATDT\T\r\c CONNECT

Doesn't your operating system have an example of a uugetty entry in the
inittab file?  Is there a setup utility that will create the uugetty
entry in inittab for dialin/dialout?

Set S181=1.  The setting of S51 will determine which speed the modem will
use.  I recommend either S51=254 or S51=253.  These "autobaud" settings
will let you dial out at any speed, while using 19200 bps (S51=254), or
38400 bps (S51=253) on dial-in.

As long as S181=1 the speed will remain locked, and as long as you have
&D3, the modem will autobaud after every call, allowing you to dial out
at different speeds without trouble.

Have you checked the S58 and S68 registers in your manual?
