This ASYNC unit implements a COMPLETE multi-port serial interface wrapped in a turbo pascal object. Baud rates up to 110,000 are supported. Up to four ports may be opened at a time, up to two ports may be active at any given time (four can be active so long as they do not share interrupts). Some considerations. A com port which shares the same interrupt as a serial mouse will over-ride the mouse driver for the duration of the program. If you have a mouse on Com1, avoid using Com3 in your program. Likewise if you have a mouse on Com2, avoid using Com4 in your program. A mouse on a BUS card will not be affected by this unit. Default addresses for the 4 com ports dictate that com1 & com3, and com2 & com4 share an interrupt on the system bus. As such while you can open both ports, make sure that only - ONE of the ports on the shared interrupt has been .ENABLED at any one time. See the .ENABLE and .DISABLE procedures for more information.
