I do not know details why you still using modems. You can provide Internet access via dialup. Just configure ppp-server additionally to mgetty (https://ubuntuforums.org/showthread.php?t=150339).
If you already have Internet at all locations and want to have terminal remote access to Linux server, you can use just regular ssh client. If you run some app that communicate with all incoming modem connections you can set that app as shell for Linux user.
I do not see any reason to have serial to IP converter. It is useful if you want to connect remotely some ancient Wyse 60 terminal that has only RS-232 interface.

So currently at Bluecross we have a pool of modems connected to a cisco 2600. What happens is when a connection is received on the modem line, the cisco router initiates an IP connection to an internal server and forwards the data from the serial line to the server. We're looking to move that Serial to IP functionality over to a Linux server so we can retire the EOL routers. Does anyone know of a way to do this? Also if anyone has any good resources for modem connectivity with linux they can forward me I'd appreciate it.
