Yes I can! Keep in mind, I have used this board to control Xmas lights, you know they blink to the music, but used dedicated windows based software which would just about never work with Hal. I will copy and paste from the DOS instructions:
Documentation for PC-RELAY Kit 74, DOS based utilities October 1995.
There are three DOS-based utilities that accompany the PC-RELAY kit:
1. RELAY used to output a hex byte to the designated parallel port
2. DELAY used to wait for a user defined number of seconds
3. WAITFOR used to wait until a specified time (HH:MM)
Batch files using these programs can be written to control the operation
of any of the eight relays on the PC-RELAY board.
The programs were written using Borland Turbo CC++\3.0. The original C
source code is also provided.
RELAY.EXE
Syntax: RELAY <hex byte> or
RELAY\1 <hex byte> or
RELAY\2 <hex byte>
Output the <hex byte> to the specified parallel port. The value of <hex
byte> can be in the range 00h to FFh.
The parallel port can be specified following the command name (see command
syntax). If none is given then LPT1 is used by default.
Example: RELAY 5A
Outputs the hex value 5A (binary 0101 1010) to LPT1, causing relays RL7,
RL5, RL4 and RL2 to operate.
They have a couple more examples listed for delay and waitfor which I don't have much use. If anyone has ideas that great. I really appreciate it.
