SERIAL_STATUS

構造体
サイズx64: 20 バイト / x86: 20 バイト

サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

フィールド

フィールド型サイズx64x86説明
ErrorsDWORD4+0+0発生中の通信エラー要因を示すフラグの組み合わせ。
HoldReasonsDWORD4+4+4送信が保留されている理由を示すフラグの組み合わせ。
AmountInInQueueDWORD4+8+8受信キューに残っているバイト数を表す。
AmountInOutQueueDWORD4+12+12送信キューに残っているバイト数を表す。
EofReceivedBOOLEAN1+16+16EOF文字を受信したか否かを示す。
WaitForImmediateBOOLEAN1+17+17即時送信文字の送出待機中か否かを示す。

HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; SERIAL_STATUS サイズ: 20 バイト(x64)
dim st, 5    ; 4byte整数×5(構造体サイズ 20 / 4 切り上げ)
; Errors : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; HoldReasons : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; AmountInInQueue : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; AmountInOutQueue : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; EofReceived : BOOLEAN (+16, 1byte)  poke st,16,値  /  値 = peek(st,16)
; WaitForImmediate : BOOLEAN (+17, 1byte)  poke st,17,値  /  値 = peek(st,17)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。
; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
