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.
