I have been working with EFX-TEK's products for years and know how to work with them in programming the Basic Stamp and Propeller. But, I am new to GCB way.

How do you send this serially in GCB
Syntax: “!RC4”, address, “S”, newStatus
– newStatus is new relay status: %0000..%1111

SEROUT Sio, OT2400, ("!RC4", %00, "S", %0001)
In this example, relay K1 will be activated, while K2, K3, and K4 will be deactivated.

Strings "!RC4" and "S"
Binary %00

Thanks for your in advance,
