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. Steve Urbach Steve has lot's of opinions.. Northern Telecom His employer subscribes to none of them.
