Hello, I'm hooking up a laptop to a Data I/O UniPak 2B Eprom Programmer and connected through a USB to Serial adapter made by Airlink. I'm using Promlink 6.10, which is the patched version from MikesArcade.com. http://mikesarcade.com/arcade/promlink.html My Settings are Com1, 9600 Baud, Parity None, Data Bits 8, Stop Bits 1 and of course flow control is off. I/O Format is current set to Absolute Binary. I've read some of the threads before on this and I seem to be running into a similar problem regarding trying to send and receive eprom data. I can do things such as blank checks, selecting devices, reading eproms, etc. 1) First of all, when I initially start up Promlink, I always get this message "16 Bit MS-DOS Subsystem - pl.exe The system cannot open Com2 port requested by the application. Choose 'Close' to terminate the application. Rather than choosing 'Close' I click 'Ignore' and get in. 2) When I read eproms, I can do so and get a sumcheck, but if I save them to a file I can't identify the file using romident. 3) When I try to send a file to the programmer I will see a progress bar quickly go to 100% and it will wait indefinitely with a "Waiting for programmer response..." message. I've also tried changing a few port settings including lowering or turning off the buffers. I'm just wondering if anyone else has been able to work around a similar problem? Up until now I've always used Windows98 and using an older version of promlink but it would be nice to use WindowsXP if possible. Thanks!
