All of the USB-Serial adapters I have encountered seem to have latency issues, in the past I have supported some engineers with laptops who used serial interfaces to some production line equipment and the only thing I could get to work reliably for them was the Brainbox PCMCIA Serial port card.

AFAIK Brainboxes repleased GPL drivers for most of their cards a while ago, check first but getting the card to work in Linux should be easy. But be warned that these cards are not cheap.
I ended up paying about £70 for my brainboxes PCMCIA card. It worked flawlessly with the kernel drivers (~around the time of RedHat 9). The PCMCIA card worked with absloutely no problems.
