modem connection

[radi_1]

Hi,i have established a connection between an hp workstaion and a pc ,on the pc,the hyper terminal is displaying rubbish texts or charachters,what seems to be the cause of that?is it something to do with the baud rate?the current baud rate is 19200 for the seriel port on the workstation and the modem and the com port on the pc.
Regards.

More likely, it is your modem setup. Not knowing the modem type, we can be of little help. But, if you refer to your modem documentation, you should get the correct setup.

Best of luck.

A lot of times it is the speed setting. Most modems have speed ratings that are the same as getty on the UNIX systems.

Set your modem to speed of 9600 or 19200.

Also make sure that the getty is responding at the same speed.

Correction, most modems have spped ratings that are NOT the same as the getty. Use 9600 or 19200. If you are doing text only across the modem, use the 9600 baud setting.

The first thing to change is gettydefs. It is more than 20 years out of date with current terminals. The default modem entries for gettydefs is to enable parity, yet virtually no terminal (or emulator such as hyperterminal) ever uses parity.

To verify this, look kat the text. Are about half of the characters correct? If so, then login but don't pay attention to the text on the screen. Enter your password and once it appears to be waiting at a shell prompt, type the command:

stty -parity

and now type some commands. That should get it working. To fix it permanently, *carefully* edit /etc/gettydefs and change all entries: CS7 PARENB to CS8. To make sure gettydefs is correct, run:

getty -c /etc/gettydefs

and a listing of the gettydefs file is produced. Look for any error messages.

check the terminal emulation setting in hyper terminal. force it to vt100 which is common and should be supported.

check the server side settings with setserial command.
