A maximum of 6 ports is supported if the existing standard COM
ports (COM1 and COM2) are included. For example, you can set one
serial port on the motherboard for COM1 (0x3F8, IRQ4), while
designating COM2-5 on IRQ3 for the four ports on a PCL-849 card.
Note:
The utility TTY, which can manipulate ports from COM1 to COM9,
is included to help users monitor and debug RS-232 communications
under Windows 3.x . It is a simple example program capable of
sending and receiving data after each port is opened with selected
communication parameters. As Windows 3.x features multitasking,
multiple windows for the ports can appear simultaneously under TTY.
However, Terminal, the application provided by Windows is limited
for the use of COM1 to COM4.
After completing the installation, restart Windows. An additional line,
"comm.drv=sercomm.drv", will appear for the PCL-849 in the [boot]
section of the Windows SYSTEM.INI file. In addition, a Windows
group "PC-ComLIB Standard COMM Driver" will be generated for
reconfiguration, driver removal, etc. At this point, you are ready to
execute applications that support Windows COMM API calls.
Windows 95 supports up to128 serial ports, from COM1 to COM128,
in the Windows 95 environment. To fully integrate the advanced
features of Windows 95, such as multi-processing and multi-thread-
ing, configure Windows 95 as described below:
1.Enter [My Computer], then [Control Panel], then [Add New
Hardware].
2.Enter [Next], then choose [N]ot to do an auto search for new
hardware.
