USB to RS232

[KenshinPT]

Hi guys,

I bought an ExpressCard 34mm to get a serial port in my laptop.

However, later I found out that the ExpressCard can be connected via PCI or USB... and that's why I am in trouble... this ExpressCard is in fact a USB to RS232 converter.

I always knew that USB<->RS232 converters work very slowly with certain devices.

Yesterday I tested this converter with some RS232 hardware I own and the data transmission is very very... very slow...

My question here is simple: This converter is based in the prolific chip, so, and does anyone knows how to get this work faster?

Regards :)

Just a suggestion, but since almost all varieties of USB are many times faster than the fastest RS232 connections, is it possible that you have failed to set your RS232 Baud rate to its fastest setting ? The only problems I have ever had with these converters are that they are sometimes not detected correctly.

RS232 is way slower than USB so your problem is quite likely to be the baud rate you using.

Thanks for the replys but my RCD programmer is still working slow :(


Well... the solution is very simple: Use a FTDI chip... :)
