Serial port not working

I'm using a recent SVN build of DOSBox in Windows 7 64-bit with a USB-to-RS232 cable (powered by a FTDI chip). I edited the conf file with:
serial1=directserial realport:COM4

The port works just fine in Windows, but when I run an app in DOSBox that attempts to configure COM1 for 9600 8n1, I get the following error from DOSBox:

Serial1: Desired serial mode not supported (9600,5,n,1)

Apparently, something got confused about how many data bits were requested.

I found a thread from 2 years ago from someone who had the same problem:
VDS Pro serial port error

But I don't know if anyone has ever found a solution. Any suggestions??

Thanks for the help!

DOSBox was mainly meant for games, so the devs didn't give high priority to serial/parallel support, although it might be nice for a few things like Populous that support head-to-head play via linking two machines through serial cables.

The only thing I can suggest is to try using a real serial port instead of a USB-to-RS232.

But that's why it supports serial port emulation over TCP/IP.
