I would like to thanks all who have sent information on this
subject.  Some progress has been made in that I am now
able to commnicate serially through a COM port using a simple
QB45 routine running in a DOS box under ME at 9600 and
inconsistently at 19200.  73, Brian

Hello Group,

Having assembled some hardware I am now trying to drive it
from the Com port of a computer.  I am not a programmer
but have used QB45.  I find that a simple QB45 routine will
run under DOS:

via COM1 at 9600Bd but not COM2 or at 19200Bd.

I assume this to be a limitation of QB45 since the computer will
successfully run a test proramme under DOS on both ports at
both speeds.

A quick look at Visual Basic cut down v4 off the front of a
magazine circa 1995 talks about MSCOMM32.  Further
a search of www turns up a vast array of information on the
deficiencies of VB and others in relation to serial communication.

Is there a later version of QB45 or variant which will successfully
run under 95/98/ME or new drivers which will allow QB45 to run?
Is it time to forget QB45?  If so which language should I start learning
(has to be simple).  Or is it time to change operating systems?

Any advice would be gratefully received.

73, Brian
