subject: Com Port Handling

-> I would like to know how to read quickly from a com port. The reason I ask
-> this is because the ah,2 INT 14h routine takes around one second per
-> character. I thought to gain the information from the i/o port of the com
-> port but as I have no information or knowledge on the function of that i/o
-> area I can not attempt to try something.
->
-> Another thing I was wondering, I also know BASIC and when you open a com
-> port you have to close it or when another program attempts to open it the
-> system will crash. In the documented list of INT 14h commands there 
oesn't
-> seem to be any type of close port command.
With a FOSSIL driver, you can do a block read/write (Int 14h, functions 18h &
19h), initialize with function 04h, and deinitialize with function 05h... 
his
isn't exactly the same as BASIC, since there you're opening a Dos-defined 
ile
called "COM1:" or similar.
