- DRSI.DOC Information file on DRSI boards for ARES/Data
-
- This file is intended for the ARES/Data sysop.
-
- Digital Radio Systems, Inc. (DRSI), of Clearwater, Florida, makes several
- packet radio adapter boards that plug directly into an IBM PC. These
- boards operate efficiently with ARES/Data since they communicate with
- the computer using the WA8DED host mode commands.
-
- The boards are called PC*PA packet radio adapters. DRSI supplies with
- the boards an important set of "terminate-and-stay-resident" packet
- drivers, named TNCTSR-S.EXE (for small systems) and TNCTSR-L.EXE (for
- large systems). One or the other of these files (you choose which) must
- be loaded before you start ARES/Data if you have DRSI board(s) in your
- system and wish to have ARES/Data utilize the PC*PA adapter(s).
- You can accomplish this easily in the ARESDATA.BAT batch file.
- Just remove the "rem" at the beginning of the lines with TNCTSR in them.
- We have had good luck with the small driver, TNCTSR-S.EXE.
-
- The TNCTSR driver makes all DRSI boards installed in the computer appear
- as one "port" to ARES/Data. Up to 32 users can be connected to the various
- DRSI boards at one time with version 1.5 of the driver. Each of the radios
- connected to DRSI cards has a "sub-port" number associated with it, such as
- 0,1,2,3, etc. When you use the "users" command for ARES/Data, the sub-port
- number is appended to the front of the callsign. This is really the only
- important difference between users connected to the DRSI port compared to
- the users connected to other TNC's on the ARES/Data database machine.
- If a callsign is sent to the DRSI board without a number and a colon, ":0"
- is assumed.
-
- Starting with ARES/Data V. 1.5, a new option is available that allows
- the sysop to select which software interrupt TNCTSR-S uses to
- communicate with the ARES/Data code. The interrupt is usually 255 (hex
- FF), and may be changed with the TAILOR utility. In any case, the value
- specified in the ARESDATA.CFG file must match that used by TNCTSR-S.
-
- More information on setting parameters for the TNCTSR utility is provided
- in the documentation that comes with the board.
-
- NOTE!!!:
- If have a fast CPU and see lots of DRSIin timeout errors, try increasing the
- PCPARETRY parameter in the ARESDATA.CFG file.
