-
- This document describes advanced new features in RELAY Gold
- version 4.0 which are NOT present in the current printing of
- the RELAY Gold User Manual. Also, certain previously
- documented features are described here in more detail.
-
- The majority of this document is intended primarily for users
- of RELAY Gold's Script Language. If you do not write scripts
- for automating RELAY Gold tasks, you should only need to read
- through page 3.
-
- To print this document, simply issue the DOS command:

-
- GENERAL RELAY Gold FEATURES
- ------- ----- ---- --------
-
-
- 1) When using VT240 graphics, you may save a graph using the script
- command "SAVEGRAPH fileid" (which is listed in the User Manual
- only for 3279 graphics). This graph may be viewed or printed
- outside of RELAY Gold using the supplied DOS command
- "VIEWG240 fileid".
-
-
- 2) When installing RELAY Gold on either two 360K or a single 720K
- floppy disk, the Color, Queue, and Tone managers are not available.
- Also, VT240, 3101-20, and 3279 graphics terminal emulations are not
- available due to disk space restrictions.
-
- There are no restrictions if you are installing RELAY Gold on a
- single 1.2M or 1.4M floppy disk or on a "hard" disk.
-
-
- 3) The COM3 and COM4 ports on a non-PS/2 system are now supported by
- RELAY Gold. To use these, use a port number of "13" for COM3 or
- "14" for COM4. Ports 3 and 4 are used for PS/2 systems only,
- which support up to 8 COM ports.
-
- Advanced users may wish to note that the port names used are
- "COM3PC" and "COM4PC". These are specified on the "Advanced
- Communication Options" screen, which follows the "Personal
- Computer Options" screen.
-
-
- 4) If you wish to have RELAY Gold answer a telephone call on a ring
- other than the first, setup the following commands in your Offline
- Profile, file "RELAY.OFP":
-
- GLOBAL &$MRINGS
- &$MRINGS = n
-
- Where "n" is the ring number to answer on (2 for the second ring,
- 3 for the third, and so on).
-
- Please note that this feature is only available with modems which
- use the "AT" command set, such as the Microcom and Hayes modems.
-
-
- 5) Expanded Memory handling has been dramatically improved in
- RELAY Gold 4.0, resulting in a reduction of the required
- base DOS memory support to as little as 128K.
-
- RELAY Gold now uses EMS memory for its communication buffers
- when there is insufficient system memory available. Normally,
- this is handled automatically based on the amount of memory
- available or that specified by the "/ST:nnn" startup option.

-
- If you desire, the selection of EMS memory may also be controlled
- manually via the new startup options:
-
- "/COEMS" means "ALWAYS use EMS for communication buffers"
- "/NOCOEMS" means "NEVER use EMS for communication buffers"
-
- NOTE: RELAY Gold requires that a contiguous 64KB page frame be
- available for EMS use.
-
-
- 6) RELAY Gold's editor may now use EMS memory for its "spill file".
- That is, parts of a file being edited which cannot fit into
- memory will be temporarily spilled over into EMS memory.
-
- In order to enable this feature, use the startup option "/EDEMS".
- That option MUST be specified when starting up RELAY Gold if
- you want the editor to use EMS memory. If you want to use the
- /EDEMS option always, place it in the DOS environment via the
- command "SET RELAYOPT=/EDEMS" (as described in the User Manual).
-
-
- 7) The YMODEM file transfer protocol is now supported by RELAY Gold.
- Various new "file protocol" values may be entered on the
- communication option screens:
-
- Y = Single-File YMODEM (also called XMODEM-1K)
- YB = "Batch" YMODEM
- YG = "Streaming" YMODEM for error-correcting modems
- YBG = "Streaming" and "Batch" YMODEM
-
- Note: Script programmers may refer to the SET PROTOCOL and YMODEM
- script commands described later in this document.
-
-
- 8) 3287 printer emulation has been added to RELAY Gold when used in
- conjunction with the RELAY/3270 mainframe software product. Specify
- a 3270 model number of "2P", "3P", "4P", or "5P" to create a printer
- session with a simulated 3287 buffer size of 1920, 2560, 3440, or 3564
- characters, respectively.

-
- ADVANCED RELAY Gold FEATURES
- -------- ----- ---- --------
-
-
- 9) The ability to create new "system" script variables has been added.
- As with RELAY Gold's predefined system variables, these user-defined
- variables are read-only and common to all sessions.
-
- To define a new system variable, use the command:
-
- DEFINE &variable = "expression"
-
- Usage Notes:
-
- A) The "expression" argument may be either a constant or
- contain other script variables. The value of "expression"
- is substituted each time the new variable is referenced.
- For example, to create a variable containing the date and
- time, do:
-
- DEFINE &DATI = "&DATE &TIME"
-
- The current date and time will be substituted each time
- that &DATI is referenced (this will NOT be the date and
- time that the DEFINE command was issued).
-
- B) A new value may be assigned to a system variable by
- reissuing the DEFINE command. Any attempt to assign a
- new value by other means (for example, an assignment
- statement) results in the creation of a local script
- variable having the same name.
-
-
- 10) The editor may now be used to edit binary files which have a
- one or two byte record length prefix before each record. For
- example, RELAY/VM and RELAY/TSO download variable-length
- binary files in this format when the NOCONVERT option is used.
- To edit such a file, issue one of the script commands:
-
- "EDIT fileid LENGTH V1" - for a 1-byte prefix
- "EDIT fileid LENGTH V2" - for a 2-byte prefix
-
-
- 11) The WAIT.COM file documented in the User Manual is no longer
- supplied with RELAY Gold. Use the WAIT script command instead.
- WAIT.COM is still available on the RELAY Bulletin Board.
-
-
- 12) The script command "SET 3270COLOR" only accepts the values "ON"
- and "OFF". The values "HIGH" and "YELLOW" listed in the User
- Manual are not supported.

-
- 13) The "/SL:0" option documented in the User Manual should NOT be
- used unless you are developing applications using the RELAY Gold
- Toolbox.
-
-
- 14) Certain 3270 emulation boards do not properly respond with screen
- changes to RELAY Gold. A new option has been added to account for
- these boards. Issue the script command "SET 3270REREAD ON" if you
- seem to be missing screen updates for the following 3270 boards:
-
- ITT Courier's "ITT IRMA 7580"
- ITT Courier's "ITT IRMA 95437i"
-
-
- 15) The SET FRAMESIZE command now accepts several alternate sizes which
- limit the amount of data sent in each block when using RELAY Gold's
- proprietary protocol. This may be useful in certain host and network
- environments. The additional sizes supported are: 64, 96, 120, and
- 240 bytes.
-
-
- 16) Certain non-standard "AT" command set modems raise the "Carrier
- Detect" signal when answering the telephone even if no modem is on
- the calling side. For these modems, RELAY Gold will display the
- Terminal Screen even though no connection was actually established.
- If you encounter this problem, you may tell RELAY Gold to ignore
- the extraneous Carrier Detect signal by placing the following
- commands in your Offline Profile, file "RELAY.OFP":
-
- GLOBAL &$MRLSD
- &$MRLSD = "OFF"
-
-
- 17) A new option has been added to the script command OPEN: Specifying
- the SHARED keyword when opening a file for random access (via the
- LENGTH option) allow multiple users to read and write the same file
- simultaneously. For example:
-
- OPEN "N:OURFILE" AS #1 LENGTH 16 SHARED
-
- Please remember that actual data written to the file may not be
- processed by DOS until the CLOSE command is used. To update the
- file contents without actually closing the file, use:
-
- CLOSE #1 TEMP
-
-
- 18) The SET PROTOCOL script command has been enhanced to support the
- YMODEM file transfer protocol:
-
- SET PROTOCOL YMODEM
-
- -- Sets file transfer protocol to "Single-File" YMODEM
-
- SET PROTOCOL YMODEM BATCH
-
-
-
-

- 10/18/89 Undocumented Features in RELAY Gold Version 4.0 Page 6
-
-
- -- Sets file transfer protocol to "Batch" YMODEM
-
- SET PROTOCOL YMODEM G
-
- -- Sets file transfer protocol to "Streaming" YMODEM
-
- SET PROTOCOL YMODEM BATCH G
-
- -- Sets file transfer protocol to "Streaming and "Batch" YMODEM
-
- The YMODEM script command sets various protcol options used during
- a file transfer. These have the same functions as the corresponding
- options documented for the XMODEM command in the RELAY Gold User Manual:
-
- YMODEM CANCEL ON/OFF
- YMODEM CHECK CRC/SUM
- YMODEM RETRIES n
- YMODEM ITIMEOUT n
- YMODEM RTIMEOUT n
-
-
- 19) The SET BREAKLEN option now accepts a value of zero. This value
- disables the transmission of all break sequences. It is useful
- with some networks and protocol converters which do not properly
- handle breaks.
