MD Previous serial to USB device (FTDI) worked fine with https://groups.google.com/d/topic/microsoft.public.fox.vfp.forms/U7PahEfJ_0E Logic 9 and my FT-5000D but device was at the netbook usb port. Purchased a USB to RS232 adaptor (Prolific) from West Mountain Radio (with serial section of the cable at the radio side) and I get the above error. Checked com port, etc, no luck. Even though I error reading hit "Ignore", the message keeps coming up and won't let me continue using Logic (why is that?/ pressing help button closes Logic, not my idea of "help"). Operating system is Win 7 Home edition on a ASUS dedicated netbook.Chuck, WA2VUMChuck, WA2VUM Back to top User ProfileView All Posts by UserView Thanks Sponsor Back to top WN4AZY #2 Posted : Wednesday, error reading comm March 7, 2012 9:26:00 PM(UTC) Rank: AdministrationGroups: Administrators, Beta TestersPosts: 1,674Location: Auburn, GAThanks: 153 timesWas thanked: 206 time(s) in 147 post(s) Prolific stuff is just not compatible. You can see if they have a later driver or something, but typically Prolific USB=>RS232 adapters do not work. This problem is well-documented, and not a LOGic problem, and nothing we can do about it. I would check to see if there is an updated driver that might improve things, but not likely. The USB=>RS232 adapters we sell WILL WORK.http://hosenose.com/stor...mp;PrimaryCatID=46& Sorry about the non-existant help for the error message. This is a message coming from Windows, and Visual Foxpro tries to call the VFP help file (which we are not allowed to distribute), and all the error would say is that an OLE error occurred or something similar that would be of no help.Tnx & 73,Dennis WN4AZYhttp://www.trx-manager.com/support.htm#43 http://forums.qrz.com/sh...am-radio-deluxe-with-USB Back to top WWW User ProfileView All Posts by UserView Thanks wa2vum #3 Posted : Monday, March 12, 2012 12:26:06 PM(UTC) Rank: NewbieGroups: Registered Posts: 4Location: Sparks.
