26 PCL-846/847 User's Manual
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-846/847
card.
Note: If using a serial mouse, it must be installed on either
COM1 (0x3F8, IRQ4) or COM2 (0x2F8, IRQ3), and
must have its own dedicated IRQ.
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-846/847 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.
