- Is there a proper group to address assembler problems too?
- If so I would be happy to address these there.
-
- I am playing with INT 14, the serial port bios routines.
-
- Function 1 is supposed to write to the port and function
- 2 is supposed to read from the port.
-
- I have my serial COM2 hooked upto a dumb terminal, and
- I can read from it just fine, plus or minus my total non understanding
- of what I am doing, but I can't get anything I write to it to appear.
- Instead I get a timeout return in the AH register.
-
- What is the timeout for? How do I get it to write the character
- I send?
-
- Thanks, Homer
