[time-nuts] Z3801A and Z38XX Issues

[Brad Stockdale]

One more suggestion... I keep a stash of DB9-TO-RJ45 and DB25-TO-RJ45
adapters around. These come unassembled. I use these on all my
Z3801A's, Z3815A's, and pretty much all other serial gear. You just
put together the adapter you need by placing the pins appropriately on
each adapter. With the right tool you can disassemble them and reuse
them, too.

modem adapter which reverses the TX and RX lines on 
one end of the cable. Also not all USB to Serial adapters work.. I 
bought an old laptop with a real serial port  at a junk computer shop 
for not much more than USB adapter to solve the RS-232 problem
