TCP/IP-TOOLS - The Complete TCP/IP Solution

TCP/IP-TOOLS is a complete TCP/IP solution for VSE/ESA users. TCP/IP-TOOLS includes a TCP/IP communication stack and a full suite of application packages. Applications available include FTP Client and Server, TN3270E Server and the Utility Bundle. The Utility Bundle includes Batch Email, LPR, Batch GZIP (compression), NTP Client and Server and the Remote Execution facility.

TCP/IP Communications Stack
BSI's TCP/IP-TOOLS includes a TCP/IP communication stack. The BSTTINET TCP/IP stack runs in a stand-alone partition (static or dynamic). No TCP/IP applications (FTP, TN3270E, etc) run in the TCP/IP stack partition. The BSTTINET TCP/IP communications stack runs in 31-bit mode and makes extensive use of access registers. The BSTTINET application will only run on VSE/ESA systems running in ESA mode. 370 mode VSE/ESA systems are not supported. The BSTTINET TCP/IP stack is optimized for dynamic partition usage. For the best possible performance run the BSTTINET TCP/IP stack in a dynamic partition and run all TCP/IP applications in dynamic partitions also.

TN3270E Servers
Our TN3270E servers both support TN3270 and TN3270E terminal sessions and TN3270E printer sessions. The big advantage of TN3270E is support for TN3270E printer clients. Using a single Win95/98/NT PC and a TN3270E printer client you can direct printed output from CICS and POWER to any network attached printer. Not just IP printers but any network attached printer. We currently are printing to several printers attached to PC's via parallel ports. Since TN3270E printer clients support multiple sessions you can drive quite a few printers from a single client. File-Transfer-Program (FTP) Client and Server TCP/IP-TOOLS contains a high performance external batch

File-Transfer-Program (FTP) Client and Server
External means that the FTP Client program runs completely outside of the TCP/IP for VSE partition. All I/O is done in the partition running the FTP client. Client indicates that this is an FTP client application and that it communicates with an FTP Server application running elsewhere on the network to facilitate file transfers. The FTP client application has been tested with several FTP Servers and conforms to RFC 959. The BSI FTP Client application can read and write data to all the usual sources (POWER, VSAM, SAM, Libraries, etc) but we have also included some special types of transfers. These include Tape Image Transfer, Phase transfers and Tape File transfers. The FTP Server also runs in a partition of its own and has very simple setup.

Batch Email Client
TCP/IP-TOOLS includes a Batch Simple Mail Transport Client (SMTP). The BSTTMTPC program runs in a VSE/ESA batch partition and allows you to send an email with one or more attachments. Attachments are in MIME format. FTP I/O routines are used so any file that can be FTP'ed can be attached to an Email.

Remote Execution Client
The BSTTREXC program runs in a VSE/ESA batch partition and in turn initiates the remote execution of a command or script. The STDOUT and STDERR output is returned to the BSTTREXC program for analysis. If the output returned is correct the VSE/ESA return code is set to zero. If the output is not correct the return code is set to 8.

GZIP Data Compression
The BSTTGZIP application provides Unix format GZIP compression and decompression of data. Uncompressed input data can be from virtually any source. Compressed output data can be written to a Library member, VSAM ESDS or SAM file. Compression of a data file prior to FTP transfer can dramatically reduce transfer times.
