Multi-Tech Systems MT5634ZLXE-T manual Modem Gets Random Errors in Transmitted Data, Connect

Your software settings may not match the settings of the remote device.

Make sure your data bits, stop bits, and parity settings match the settings that the other computer is using. The two most common settings are: 8 data bits, None parity, and 1 stop bit (8,N,1) or 7 data bits, Even parity, and 1 stop bit (7,E,1).

If the telephone line is very noisy, you may see corrupted data on your screen.

Due to poor telephone line conditions, the modem may have fallen back to a slower communication speed. You may need to change the baud rate setting in your software to match this slower speed. To return the modem to the higher speed, disconnect the link and re-establish again.

P:When Using V.42bis or MNP5, Some Features Are Disabled

C: You may be using a non-streaming protocol, like Xmodem or Ymodem to transfer files. Those are fine unless you are using V.42bis or MNP5

S: When using V.42bis or MNP5, you should use a streaming transfer protocol like Ymodem-G or Zmodem.

S: Configure your software to use hardware flow control (RTS/CTS ON).

Q:When Connecting to Another Modem, the Modem Reports a Higher Connect Baud Rate than it Is Really Using

C: The modem defaults to report the modem-to-computer baud rate when it responds with

CONNECT.

S: Go to Command mode with your communication program (like Telix) and type ATW2, then click Enter. This tells the modem to report the modem-to-modem baud rate instead.
