+.SH NAME
+read \- Read from a channel
+.SH SYNOPSIS
+\fBread \fR?\fB\-nonewline\fR? \fIchannelId\fR
+.sp
+\fBread \fIchannelId numBytes\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+In the first form, the \fBread\fR command reads all of the data from
+\fIchannelId\fR up to the end of the file.
+If the \fB\-nonewline\fR switch is specified then the last character
+of the file is discarded if it is a newline.
+In the second form, the extra argument specifies how many bytes to
+read.  Exactly that many bytes will be read and returned, unless
+there are fewer than \fInumBytes\fR left in the file;  in this case
+all the remaining bytes are returned.
+.PP
+.VS
+If \fIchannelId\fR is in nonblocking mode, the command may not read
+as many bytes as requested:  once all available input has been read,
+the command will return the data that is available rather than blocking
+for more input.
+The \fB\-nonewline\fR switch is ignored if the command returns
+before reaching the end of the file.
+.PP
+\fBRead\fR translates end-of-line sequences in the input into
+newline characters according to the \fB\-translation\fR option
+for the channel.
+See the manual entry for \fBfconfigure\fR for details on the
+\fB\-translation\fR option.
