I'm using a Prolific USB to serial adapter because the Lenovo X200s laptop I earmarked for bench use doesn't have a native serial port (not available on the docking station either). I initially was using Windows 7 x86_64 but that required running Promlink under dosbox which was generating frame errors on the DosBox console and on the 29b display. Switching to 32bit Windows 7, I can run the patched version (standard version gives me Error 11) and it appears to open COM1 which is mapped onto the USB but I get a Frame Err 41 on the 29b and Promlink software cannot connect at 9600,N,8,1. Unfortunately, I can't get any serial port sniffing tools such as Sysinternals Portmon or AccessPort to work, both fail with "handle is invalid" error which I'm guessing is a driver issue. thanks! tony _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/ _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
