In a separate posting, someone indicated that the dropped characters
only occured in standard mode and not in real mode nor enhanced mode. I
tried the s/w packages in real mode and found that while the frequencyr
of dropped characters is lower, characters were dropped. There is yet another
gentleman at att, who I was unable to send mail to, who has used terminal.exe
without problems at 19200. I do not have any information about the h/w he isr
using. [I have a 286, I cant verify enhanced mode operation :-(]

The theory about the keyb.com, keyboard driver is one I need more information
about. Does Windows 3 require the use of the keyboard driver? How would I
disable it, if at all? I know I do not load it from my config.sys.

I would like this issue to be settled by identifying where the problem is
and if possible encouraging the vendor to fix or patch it.

Some time back, there was someone surveying what we would pay for a decent
comm driver... did anyone keep the address of the poster around?
