You can buy a serial port adaptor card are that fits in a PCI slot.
But this assumes you have a desktop PC with a PCI slot.

The cards are cheap, they start at about $10.  I'm shopping for a four
port card and they are only a bit over $20.   Seems I'm collecting
serial devices.  I have two GPSes, a Motorola "Oncore" and a Trimble
"Thunderbolt".  The Rubidium oscillator needs rs-232 also and I just
finished a PitTic II.   (

I bought an Intel "Atom" powered motherboard.  This thing uses so
little power there is not cooling fan.   At my cost for power the 85$
computer will pay for itself in 2 years.  It was cheaper to spend the
$85 than to use some old free PC.
