I know this is a bit off-topic, but I was playing around with the DECDLD commands in the VT220 programmer's reference guide to make character graphics on the VT220 (I'm actually using Mac240, a VT220 emulator that has full DECDLD support at a VT220 level) I'm having a problem getting characters to join at the top of the cell. The top two pixels don't seem to meet. I see some material about VT320 but the addressing of the matrix seems quite different on that terminal. I'm using 7-bit encoding to create the characters. Do I need to use 8-bit in order to use the full matrix? I'd be surprised if anyone on here has actually messed with this, but I thought it was worth a shot. I can also toss my work at whoever has a VT220 lying around to see if they can test it as well. Any input is appreciated (as long as I can decode it, ha ha) Julian
