- COMM180
- Modem/SCSI Peripheral Board
-
-
-
- The Micromint COMM180 expansion board may be the only board
- you will ever need for your SB180 computer. This 4" x 5" board
- adds two major functions to your SB180:
-
- 1) Bell 103-212A compatible 300/1200 baud modem
- with Dual Tone Multi-Frequency (DTMF) encode/decode
- capability and voice synthesis
- 2) SCSI hard disk controller interface
-
- The COMM180 board is available in three versions:
-
- 1) Modem, DTMF encode/decode, and voice synthesis alone
- 2) Small Computer System Interface (SCSI) hard disk
- controller interface alone
- 3) Both of the above
-
- And either the modem version or the SCSI controller version may
- be upgraded to the full version at any time.
-
- The COMM180 does not use a serial port on the SB180, but
- instead addresses the bus directly. It is fully Bell 103 and
- Bell 212A compatible (including FCC registered Data Access
- Arrangement) for 300 and 1200 baud use, is 8251A software compat-
- ible, features both DTMF and pulse dialing, call progress mon-
- itoring, DTMF reception and decoding, and a unique diagnostic
- capability which automatically compensates for common telephone
- line deficiencies. In addition the COMM180 has optional voice
- synthesis capabilities which allow it to respond verbally to
- commands entered via the standard touch tone telephone pad.
-
- The SCSI allows the use of a wide variety of hard disks with
- the SB180 for fast, sophisticated mass storage whether you need
- just 5 megabytes or 50 megabytes. Many manufacturers offer hard
- disk drives and controller cards which mate with the SCSI inter-
- face. If you need more file space than floppies allow, the
- COMM180 board can help meet your storage needs. In addition,
- many laboratory instruments support the SCSI standard, thus the
- COMM180 can allow the SB180 to be more easily used for data
- logging and data reduction.
-
- Software for the COMM180 includes a complete modem commun-
- ications system and messaging system designed to run under Z-
- System DOS available for the SB180. BIOS modifications are
- supplied in source code to allow integration of hard disk drivers
- into the Z-System DOS.

- COMM180 Software
-
-
- The software which comes with the COMM180 consists of TERM
- III and Z-MSG (optional).
-
- TERM III is a sophisticated communications package which
- offers all the functions of standard modem programs but goes far
- beyond them when used with COMM180's advanced features and Z-
- System DOS (required for operation). TERM III was designed to be
- used as:
-
- 1) an originating communications system to allow the user to
- dial out, communicate with other computers, and perform
- file transfer functions;
- 2) a remote access system to allow users to dial into the
- system, interact with it, and transfer programs into
- and out of it; and
- 3) a configuration system to allow the user to configure the
- attributes of the other two types of systems.
-
- TERM III offers multiple file transfer protocols: Christiansen's
- MODEM7 (with checksum and with CRC), MODEM7 batch, XMODEM, KER-
- MIT, CompuServe's CIS, and X-ON/X-OFF. Special attention has
- been paid to making the remote access system completely secure
- from unauthorized use. You may also call in to TERM III on the
- COMM180 and use a standard touch tone pad to give special
- instructions, e.g., run a program using the COMM180's speech
- synthesis to give a verbal summary of system access.
-
- Z-MSG allows the COMM180, SB180, and TERM III to be custom
- configured as a "turnkey" Remote Bulletin Board System - either
- as a public system allowing access to anyone or as a private
- system restricting access to "members only". Z-MSG allows up to
- eight user "types" with varying priveleges associated with each.
- Messages may be public or private and may be over 100 lines long.
- Extensive editing functions are provided and comprehensive on-
- line help is always available.
-
-
- For those wishing to use the SCSI as a hard disk controller,
- source code is provided which allows many types of hard disk
- controllers and sizes of Winchester disks to be used as mass
- storage for the SB180. Two popular controllers are supported
- directly - the Xybec 1410 controller and the high performance
- Adaptec ACB4000. Two disk sizes are supported - the standard 10
- MB drive as well as the high capacity 20 MB drive. Provisions to
- support other controllers and even higher capacity drives are
- included. Of course, the SCSI may also be used to link other
- SB180's or SCSI equipment together as well.
