I have used the short routine shown here
http://www.solivant.com/altair_bootloaders/index.php?album=altair_bootloaders&pagen=1
To check my serial port, prior to enter the bootstrap loader for loading Basic on my Altair 8800b.
I have found that when i press RUN the machine hangs. Thereafter Pressing reset does not have any effect. I need to power down the system to regain control. On the trminal side I cannot see any activity either (using teraterm).
My serial card is a SIO2. The test program is loaded at address zero, i have double checked it is correctly entered. Other boards present in the system are two 16Kb static ram.
Could the SIO by itself hang up the system this way?
