USING BITCOM'S V.42/MNP

The 6.X version of BitCom is designed to emulate the V.42bis, V.42 and

To use BitCom's software-emulated V.42bis, V.42 and MNP, set the V42 field
in the Communications Parameters menu to YES .  If the systems you make a
connection wit does not support V.42bis, V.42 or MNP, BitCom will
automatically "fall back" to a normal connection with does not support
V.42bis, V.42 or MNP, BitCom will automatically "fall back" to a normal
connection.

NOTE:  BitCom's V.42bis, V.42 and MNP emulation only works with the 
       modem that BitCom came with (or other modems that use the
       Rockwell 225 chipset).

MAKING A DIRECT CONNECTIONS (MODEM TEST)

Using BitCom's Direct Connect Mode, you can send Hayes Commands directly
to your modem.  You can use this mode to make a direct connection with
another computer (using a cable instead of telephone lines and a modem).

1.  From the Communications Selection Menu, select the record "dumb
    terminal, local connection".

2.  Select the connect command.

    You are now ready to communicate with the other computer or send
    Hayes commands to your modem.  To test the modem, type ATI and press

    modem, type ATZ.

USING COM3 OR COM4

Two COM ports cannot share an IRQ line at the same time.  For example, you
cannot set your modem to COM2 and your mouse to COM4.  To solve this
problem, BitCom lets you set COM3 or COM4 to IRQ5,  thus avoiding any
conflicts with COM1 or COM2, and allowing you to use a third serial
device.

To change the IRQ number of a COM port, open the Communications
Configuration Menu and select the SET IRQ command.  In the Assigned column
of COM3 or COM4, use your left or right arrow key to toggle to IRQ5.

CLOSING BITCOM

To quit BitCom, return to the Communications Selection Menu and select
the Quit command.
