I mentioned this to the OP but did not see it mentioned here: That Lantronix above is $214 for one serial port. Money sensitive people might consider an EdgeRouter Lite (used only to get ssh and provide firewalling) coupled with a used Portmaster PM25 off Ebay for under $200 (total) for 25 serial ports.
