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.
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.
