I've had this problem with my hardware serial port since I built it.
One time and one time only, I was able to get the hardware port to
communicate with the Elf2000. I have no problem getting the software
port to work but I'd like to get the hardware port to work too. The
Disk board is fully populated and the CF card works great. The one
time I got the hardware port working, the SHO TERM response
was=BAUD1=0x01 BAUD0=0x32. I looked at the lines with my oscilloscope
and the 16C450 XTAL1&2 signals looked good, BAUDOUT and MAX232 C1 & C2
signals looked good. Any ideas on what is keeping the hardware port
from initializing reliably? The SIN and DSR pulses are making it to
the UART. Anyone out there having problems with connecting through the
Also, was the BAUD0=0x32 to be expected when it did work that one time?
