Hi. After talking with someone at Traveling Software, it seems that part of my problem is that, when booting with a DOS 5.0 floppy, I do not have access to the COM1 port, i.e., after booting into DOS, if the first thing I do is: A:> echo dir >com1 I get: Write fault error writing device COM1 Abort, Retry, Ignore, Fail? When I try the same thing after booting into Windows NT, I get no errors. According to the guy at Traveling Software, I should be able to do this from DOS without error. This may be a purely DOS question, but does anyone know why this would be failing? Are there any fixes? Thanks for any help.
