I have a USB to serial converter and a picaxe 18A. When I attempt to download a program I get error: serial port error code 0x1F54 error reading comm device. I know the USB to serial converter works because I had it connected to a modem previously. The proper com port is selected. Any ideas?

not all USB to serial convertors are compatable As the chipset needs to support break command. Which chipset does the convertor use? Also are
You sure the wiring to the chip is correct?

OK, so at this point you dont know if either the cable or the picaxe has been damaged, or some other reason, unless you have more than one picaxe chip?
Are you able to make a serial cable to prove either way?
I,m sure I,ve wired up my usb cable incorrectly at some point in the past and caused no damage, perhaps I was lucky.

The device manager shows Prolific USB to Serial Comm Port (COM4). It was installed with the tiny CD that came with the converter. I just purchased hyper terminal and retested the com port using no handshake serial loop back (pin 2 conected to pin3). That works fine.
