I'm looking for a modem that will maintain a constant baud rate to the terminal regardless of the speed used to connect with the remote. I am using a DecServer 200 to reach my modems. The DecServer will not let me change a ports output speed, so the modem sees a constant speed from the terminal. Changing the output speed in VMS has no effect. I need to connect with a modem which uses a lower baud rate than the terminal to modem connection is running. I believe I need a modem that will not change its output to terminal baud rate while maintaining a lower baud rate connection to a remote. Anyone know of such a modem? Thanks for any info, J.

Michael Cherry We are currently using the Multi-Tech 224ER rack mounted modems. They have a feature called 'baud adjust'. This allows us to have our Vax 8650 ports set at 9600 baud and the modem serial port is also 9600. The modem baud rate always adjusts to the originating modem. This way users from 300 baud to 2400 baud with data compression can call the same number. The modem does buffering, flow control, etc. I've got about 70+ of these on line. They are very reliable and flexible. They also make a stand alone model. University cost is about $400.00.

I tried to send this reply to Mike Cherry directly, but his retrun address "mgh-coffee!cherry@husc6.harvard.edu" doesn't work (husc6 doesn't know who mgh-coffee is). ------------------- There are a lot of modems that will let you set them up this way. Most modern (well-designed, last 5 years) modems have this feature. The specific modems we use that do this are USRobotics Courier 9600HST modems, I'm pretty sure the rest of the Courier line does it too. __ /| /| /| \ Michael A.
