+Citadel currently  expose APIs for streaming into a process' `stdin`. only  withPTY and withTTY.
+
+An example of how pty model can be used:
+
+```swift
+try await client.withPTY(
+        SSHChannelRequestEvent.PseudoTerminalRequest(
+            wantReply: true,
+            term: "xterm",
+            terminalCharacterWidth: 80,
+            terminalRowHeight: 24,
+            terminalPixelWidth: 0,
+            terminalPixelHeight: 0,
+            terminalModes: .init([.ECHO: 1])
+        ),
+        environment: [SSHChannelRequestEvent.EnvironmentRequest(wantReply: true, name: "LANG", value: "en_US.UTF-8")]) {
+        
+        ttyOutput, ttyStdinWriter in 
+        
+        ...do something...
+}
