[Elecraft] USB to serial angst

[N2TK, Tony]

That is exactly how I got a serial port in my Dell Optiplex. Found it on the
motherboard and made sure it was listed in Bios.

A lot of PCs that "don't have a serial port" actually do have the
electronics on the motherboard.  If so, you can mount your own DB-9
connector on the rear panel and wire it to the motherboard.

The motherboard connector is often a 10-pin (two rows of 5 pins) header
with one pin removed to give a one-for-one correspondence to a 9-pin
RS-232 connector.  If you can't find the COM ports in Windows, you might
have to check the "integrated peripherals" section of the BIOS to see if
the manufacturer has disabled serial ports in the BIOS.

It might be worth a look before going out and buying a serial PCI card
(or a new computer).
