Serial / Modem

GSSquared includes a virtual Hayes-compatible modem you can attach to a serial port. From Apple II terminal software it behaves like dialing out over a phone line — except the “number” is a TCP host and port on the internet.

What you need

  1. A serial port: IIgs built-in SCC, or a Super Serial Card in a slot.
  2. That port’s attachment set to Modem — see Serial & Parallel Connections.

How to dial

Use any normal serial program (ProTERM, Spectrum, TelCom, etc.). Example:

ATDTcqbbs.ddns.net:6800

That connects to host cqbbs.ddns.net, TCP port 6800.

How to hang up

Send the Hayes escape sequence, then hang up:

+++
ATH

(Wait about a second of silence before and after +++.)

File capture, clipboard, or a real serial port

Set the port attachment to File to save serial output to a host file (a toast shows the filename when the file closes). Clipboard copies the captured/printed text to the host clipboard on close. Serial attaches a real host serial port. Details: Serial & Parallel Connections.
