5.5 Multiple COMM Port and Modem Server Support in Across the Boards/DOS
MAINCON Configuration Panel: D1: “Comm Port Assignments”
Version 3.06 of
Across the Boards
adds support for multiple COMM ports (ports beyond COM1 and COM2)
and NASI and INT 14 based modem servers (also known as async gateways). A new MAINCON configuration
screen allows the configuration of COM1 through COM15. If no special configuration is entered for COM1 or
COM2, the standard PC COM1 and COM2 ports are accessed. Accessing other COMM ports requires
configuration.
Multiple COMM Port Support
Version 3.06 of
Across the Boards
includes support for async serial ports above “COM2”. Prior versions were
limited to either COM1 or COM2. To configure an extended serial port, the following steps are required:
1.
As has been done in the past for serial communications, select option “D2”, “D3”, or “D4” from
MAINCON’s primary menu (for IBM 3101, VT100, or Tymnet78 support respectively).
2.
The configuration screen for the chosen protocol converter will appear. For the “COMM port”
specification, specify “3” to “15”. Press F10 to write the configuration file; this will return you to
the primary menu. (Alternatively, the COMM port may be specified at the XAPI open or in a
DIALOG script).
3.
Select option “Communication Port Assignment” from the primary menu (D1).
4.
In the configuration line corresponding to “COM3” (or whichever port was configured in step 2),
enter “COMM” in the TYPE field. You will be presented with two additional fields: “I/O Port”,
and “IRQ”. The appropriate values for these fields vary by hardware configuration; a help screen
may be obtained by pressing F1 which presents guidelines for configuration.
Enter the appropriate values in these fields, then press F10 to write the configuration file.
The configuration is then completed.
NOTE
: It is possible to alter the I/O port and interrupt assignments for COM1 and COM2, but this may
lead to confusing configurations and is therefore not recommended (for example, the user could swap
COM1 and COM2). If no special configuration is supplied for COM1 and COM2, the standard values
will be used.
Configuring NASI (NetWare Async Services)
NASI based modem servers (available from Novell and numerous other vendors), use an INT 6B API.
Configuration for NASI is similar to the preceding example with the following exceptions:
1.
The choice of COMM port is not significant (1-15 may be used).
2.
On the “Communication Port Assignments” configuration screen, specify type “NASI” for the
COMM port you have chosen.
3.
You will then be prompted for “Name”, which must be the resource name for the NASI server.
Contact your LAN administrator for this information.
Configuring INT 14 Drivers
INT 14 based modem servers use a variant of the PC-BIOS INT 14 serial port API. Most vendors provide their
own extensions to the BIOS INT 14 API.
Across the Boards
can be configured to take advantage of some of
these dialects.
