Someone on Lemon64 made a guide for the MSS-100 configuration. There are also links in the post to configuration settings that I use. They will probably answer all your questions. :thumbsup:

Good luck! Feel free to send me a PM if you have any other questions.

For the last 2 months or so, I've been messing with this MSS100 on the weekends & getting no where. I've followed that walkthrough you suggested, actually had done so previously, prior to posting. I don't understand why I can't get any data across the serial connection. I am using multiple cables, as I previously stated, all of which give me no results. I have reviewed numerous documents on configuring the MSS100 device, I've reset it to factory defaults, gone through the configuration, & am using multiple computers & multiple cables that I can use other serial devices such as modems without any issue. At what point is it safe to assume this thing is defective, & I wind up dumping more money into another one?
Currently I have a USB->Serial adapter on Linux, I've used minicom, syncterm, & cu to attempt to connect, each time power cycling the lantronics & re-configuring the USB->Serial adapter to avoid any configuration or lock-creep.

I am initializing on Linux with :
stty -F /dev/ttyUSB0 9600 -cstopb -ixon -ixoff -crtscts -parenb echo
Reviewing with stty -a -F /dev/ttyUSB0 gives the following :

The reason that I'm using Linux is this gives me the most troubleshooting information, & the most control over the device. The DOS machine that I intend to use this on leaves me blind, only wondering why I get init failed back. I have yet to find a way to "initialize" the mss100 as a modem, & successfully issue AT commands to it. I'm kind of at my wits end with this... as the serial port is giving me nothing out, yet the tcp/ip side has been working fine from day one. It's incredibly frustrating as nothing I'm doing is giving me any indication of life (other than RING when telnet in, & sending ATA does nothing), despite following walkthroughs of others getting it to work. However, of the walkthroughs I'm following, these people are using 8bit Atari/C64 machines, & not 16bit DOS. Does this matter for RS232? I would think not, but what about the pinouts? Just so many inconsistencies, & all I know is that it's not communicating.
Just to add to the cable confusion :

6: Troubleshooting
--The MSS completes its power-up and boot procedures, but there's no noticeable serial activity.
--Check the terminal setup and the physical connections, including the cable pinouts (see Pinouts). Try another serial device or cable, or cycle power on the MSS.
Then under section 7 is the pinout diagrams. I'm trying to compare those pinouts vs what would be in a generic null modem cable referencing here :
