[comp.sys.ibm.pc] Windows and COM1:

johnson@c10sd1.StPaul.NCR.COM (Wayne D. T. Johnson) (04/22/88)

I am about to start a large programming project using MS windows (probably
not 386).  One of the crittical problems we need to have in this program
is that we need to receive data at 9600 baud un-paced (no X-ON/OFF or ACKS
allowed) and at the same time stash this data on disk.  I have done this
small mirecle before but without windows and by writting a 8250 device
driver that would "block" incomming data in forground (interrupt state).

Now, the question, what resources does windows have for the communication
line, more specifically, does windows have a smart enough driver to handle
the com port or will I need to write my own?  How would windows multi tasking
help/hinder us.

Please E-MAIL responses and I will summerize.
