RAD lists a V.24(rs232) to V.36(RS449) converter MIC 24/36 your MCP port
is DTE so the pn is MIC 24C/36T Telephone (201) 587-8822 is head office,
I've seen  their products in various catalogs.

BTW your MCP is an ALM-2 with different I/O connectors and a few jumper
changes :-).  you did not mention if you needed sync or async operation?
MCP and tty[a|b] support sync/async, the ALM-2 give yo more async only
ports.
