EMS0017 REDIRECTION OF LPT1. PCJR INTERNAL MODEM REDIRECTED
10/23/85
IBM PCjr (4860067)
A base model PCjr with no internal modem and no parallel
printer adapter automatically sends output intended for
LPT1: to the serial port (for the Compact printer). Hence,
the use of the serial device is transparent to the user.
This serial port is also COM1: with no options installed.
If an internal modem is installed the serial port then
becomes COM2:. Under these conditions the printer output is
then sent to the COM2: serial port (the Compact printer).
This is handled automatically by ROM BIOS.
If a parallel printer adapter is attached, the output
intended for the printer is automatically sent to the newly
attached parallel printer. To use the Compact printer,
output must be redirected to the serial port.
MODE COM1:1200,N,8,2,P
MODE LPT1:=COM1:
The above two DOS commands work on a PCjr without an
internal modem. COM2: is used when the modem is installed.
