[comp.os.os2.programmer] Codeview <-> terminal I/O

hb@ddsw1.MCS.COM (Henry Barta) (10/17/90)

Hi there (again)

I am debugging a multi-threaded full screen non-PM ("VIO" for the time
being) task that has one compute bound (Continuous I/O to an 8514/A 
adapter), one unbound (delay 250 millisec, write to 8514/A adapter,
repeat), and one I/O bound (read keyboard) task. The compute bound
thread runs at 'normal' priority while the unbound thread runs at 
'time critical' priority. When run under Codeview, the I/O bound thread
takes about 8 seconds to respond to a keystroke. I have tried running
this thread at 'normal' and 'time critical' priorities with no change.
Is there a known work around for this problem?




Thanks in advance. Post or E-mail as you see fit. (I will summarize
E-mail responses)

Which version of CodeView are you using?  The latest lets you freeze threads
from the keyboard.  I guess what I am trying to say is that the time-critical
thread is probably eating up the cycles...

Cheers,
