I just added a Radius 16 accelerator to my Mac+ and I'm now having problems using my DeskWriter. Any time I print more then one page of text, the printer will print the first page, then bomb out with a "Datacomm buffer overrun - no DTR handshaking." I have check the cable, connections, connectors, and even tried a shorter cable. No Luck. Before the upgrade, the printer would wait for the Mac, now it appears to be the other way around. Help! I'm not sure who's at fault, the printer/driver or the accelerator not passing SCC interupts fast enough. My Configuration is: Macintosh Plus 4 Megs Radius 16 (68020 16mhz, no fpu, Rev 2.0+, driver rev 2.5) HP DeskWriter Seagte 80mb 28ms I have considered hacking up an init to slow down the output, however, this is less then desirable. The DeskWriter run at 57.6k baud, and I'm not sure it's using the serial driver. Please e-mail any ideas, I will summerize them and post them. -- Neal E.
