 		 #156819 - feed through that wasn't
Responding to: ???'s previous message
It was a hardware problem. This new board had a feed through from top to bottom of board that was open.

Back to the software.

Before I MOV the value in 43H & 44H to the SBUF I set their values somewhere else in the software..

for example:

MOV 43H,'6'
MOV 44H,'-'

Which I assume places the ASCII value of the number 6 and the space "-" character into the registers.

The printer prints the * and W characters but not the values put into 43H and 44H, and doesn't LF blank spaces like it is even trying.
