GENERIC MODEM (AND OTHER) INFORMATION
-------------------------------------
When a modem is set for VARIABLE serial port rates, the
modem will shift its rate to match the connecting modem's
rate. The communication software, in this case MegaHost,
must also match this connect rate. MegaHost does this when
LOCKBAUD=N in the MEGAHOST.CNF file. The BAUD= entry should
be set to the highest connect rate, currently 19200 for
14400 bps modems.
If a modem is set for FIXED serial port rates, the modem
does not drop down to match the lower connection rate. This
allows you to lock in at a higher rate for more efficient
communications. If the modems connect using data
compression, you can more then triple your throughput. This
is handled in MegaHost by setting LOCKBAUD=Y in your
MEGAHOST.CNF file, and setting the BAUD= entry to the
highest baud rate your PC will handle. Most PC's will
handle 38400, and some 57600. (Use 38400 if you have ANY
problems with your connections.) NOTE: When a user calls
MegaHost and LOCKBAUD=Y, pressing the "S" key to stop
displaying text screens appears to have no effect. This is
because the data has already been buffered in the modem and
MegaHost has lost control.
MegaHost works well with the following settings:
Enable CCITT answer sequence
Disable Software Flow Control
Enable Hardware Flow Control - CTS, RTS
Force on DSR
Enable Display Result Codes
Disable displaying Extended Result Codes (ARQ)
Locked or fixed serial port rate (LOCKBAUD=Y)
CD not forced on (normal)
DTR not forced on (normal)
Enable Data Compression
Enable Error Control
Variable Data Rate, Phone Line Interface (normal)
Sometimes the hardware MegaHost is running on requires
MODEMDELAY= increased.
