[gentoo-user] Slow connexion with usb to serial converter

Hi,

I'm trying to use usb to serial converter, the data transfer works but it's
very very slow.

I use FTDI converter with kernel 2.6.25-r7 build in driver.

How could I trave where the problem comes from?

Thank you,

Unless you give more information one might assume that your slowness  
is only that inherent in a serial connection.

Stroller.

Ok,

The problem is I don't know what kind of information I can give.

What I can say is the transfer takes 10 minutes via usb to serial instead of
30 seconds via the standard DB9 connector.

It sounds like you're saying that the USB->RS232 serial connector is slower than a real RS232 port - is that right?

Are you using the same program with both types of serial port?

FWIW, i'm finding my USB->RS232 a poor substitute for a real RS232 port for doing some things.
