I'm trying to use a DOS program which accesses the COM1 port. I get the error messages "Unhandled INT 14 call 2" and call 3 repeated over and over whenever the program trys to access COM1.

here are my config settings:

[directserial]
# directserial -- Enable serial passthrough support.
# comport -- COM Port inside DOSBox.
# realport -- COM Port on the Host.
# defaultbps -- Default BPS.
# parity -- Parity of the packets. This can be N, E or O.
# bytesize -- Size of each packet. This can be 5 or 8.
# stopbit -- The number of stopbits. This can be 1 or 2.

directserial=true
comport=COM1
realport=COM1
defaultbps=9600
parity=N
bytesize=8
stopbit=1
