or someone else can interrupt the connection by picking up another
phone. If this is a frequent problem, disconnect the extension phones
before using the modem, or install another phone line specifically for
the modem.
•
Check for loose connections between the modem and the computer,
the telephone jack, and AC power.
•
You may have had a poor connection because of line conditions or the
problem may have originated on the other end of the line. Try again.
•
If you were online with a BBS, it may have hung up on you because
of lack of activity on your part or because you exceeded your time limit
for the day. Try again.
The Modem Cannot Connect When Answering
•
Auto-answer may be disabled. Turn on auto-answer in your datacomm
program or send the command ATS0=1 to your modem in terminal
mode.
File Transfer Is Slower Than It Should Be
•
You may have an older UART. For best throughput, install a 16550AFN
UART or a Multi-Tech ISI serial port card. See the "Quick Start"
chapter for information on how to identify your UART.
•
If you are running under Windows 3.1 and have a 16550AFN UART,
you must replace the Windows serial driver, COMM.DRV, to take full
advantage of the UART's speed. (See "The 16550 UART and
Windows 3.1" in MultiModemZDX Help.)
•
If you are using a slow transfer protocol, such as Xmodem or Kermit,
try Zmodem or Ymodem/G instead.
•
Is your line noisy? If there is static on your line, the modem has to
resend many blocks of data to insure accuracy. You must have a
clean line for maximum speed.
