OSMKGWMC - DOS APPLICATION LOSES MODEM ACROSS SUSPEND ON GATEWAY SOLO
11/08/96
=======================================================================
DOS Application Loses Modem across Suspend on GATEWAY SOLO
=======================================================================
Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------
DESCRIPTION
DOS applications, such as ProComm, lose the connection to the modem
after suspending and resuming a Gateway Solo laptop computer, equipped
with a PCMCIA modem. The problem occurs both on OS/2 Warp 4 and on a
DOS-only system.
When the problem occurs, the Plug-and-Play object in the OS/2 System
folder displays the COM port for the modem, indicating that the modem
is connected. The MODE COMx command (where x is the COM port displayed
by the Plug-and-Play object), entered at the DOS prompt, correctly
returns the status of the modem COM port, indicating that the modem is
connected. However, the application is unable to detect the modem until
it is closed, the PCMCIA modem is ejected and reinserted, and the
application is restarted.
RESOLUTION
1. Display the Gateway Solo BIOS Setup page:
a. Open an OS/2 window.
b. Press Ctrl+Alt+Esc. (If it is a Mini Desktop computer, press
Ctrl+Alt+S.)
If these key combinations don't work, refer to the User's Guide
that came with the computer for a description of how to display
the BIOS settings. The BIOS settings are also referred to as the
CMOS setup.
2. Turn off Backlighting on the LCD screen.
The DOS connection problem goes away both in the real DOS environment
and in the OS/2 Warp 4 DOS emulation.
