I would like to be able to send a stream of data from my non-USB laptop to my USB desktop. I bought a USB<->Serial converter and a serial gender changer to try to do this. When I plug in the USB end to my HP Pavilion 503n running CentOS 5, my lsusb says this:
Bus 003 Device 004: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
As well, a /dev/ttyUSB0 appears. The other end is connected via gender changer to a female serial port on a Compaq LTE 5100 running Debian Etch. The problem is that when I do this:
Serial end: cat /dev/ttyS0
USB end: echo hi > /dev/ttyUSB0
The echo on the USB end completes, but nothing appears on the serial end. Sending data the other direction doesn't remedy the problem either. Moreover, I tested this on my main machine, and it had the same result. Fortunately, no system lockups happened during any of the tests.
I'm guessing the problem is that the gender changer doesn't rearrange the pins so that it can communicate this way (on both sides, I see 54321/9876). My question is: am I missing something else? Are my parts defective?
