flashing Dectalk under Dosemu

Hi all. I've since acquired some firmware I want to attempt to flash onto this thing, so as to fix a rather annoying bug (or try to, at least). I ran the install.exe for the Dos drivers with 
no problem; it dumped everything into c:\dtexp under~/.dosemu/drive_c. However, I can't get comchk.exe to find the Dectalk on ttyS0. I've check dosemu.conf, and so far the only relevant serial 
port setting is which port to use (I've set it to /dev/ttyS0, which is the correct port). I then figured that the fact that the Dectalk wasn't being found on that port might have to do with 
the Linux serial driver not being used vs the Speakup one, therefore I got everything working within Minicom as a test. Unfortunately, comchk.exe still returned the error about not being able 
to find a Dectalk express on Com1. If I attempt to run the firmware loader at this point, would the Dectalk be found on the correct port, or do I have to get comchk to return success first? 
Perhaps something in dosemu.conf I overlooked/forgot to check? I really don't want to somehow turn this synth into a paperweight, by perhaps managing to upload half its firmware to it. If 
anyone that has done this before under Dosemu, could perhaps point me in the right direction as to what I'm missing, I'd really appreciate it. Thanks!
